A preseason look at the stats that matter for Indiana

IUPSU0014

While it’s true talent is the biggest factor in winning big at any level in sports, there are also numbers and trends that we can correlate to success. Advanced statistics are the reason why Ken Pomeroy’s ratings are often more predictive than any top 25 poll or preseason prediction.

This preseason, Indiana is being picked all across the board and the season that lies ahead holds more uncertainty and intrigue than last for a variety of reasons.

Among them:

- The Big Ten, beyond Wisconsin, appears to be wide open.
- Indiana underwent major roster turnover for a second straight offseason.
- Indiana added several players who appear capable of shoring up a major 3-point shooting deficiency.
- Indiana lost the best rebounder in the conference and it’s fair to ask: “Does this roster possess the pieces to replace that production?”

All of those themes and questions will come more into focus over time as the games are played and the season rolls along. It’s quite possible the Big Ten will have a more defined hierarchy than many believe. It’s also possible that Indiana’s shooting will be better (or worse) than many are predicting. And the rebounding and roster turnover pieces may (or may not) play as big of a role as we think.

But as we study the numbers and look at what it’s going to take for Indiana to be successful this year, several things stand out. Here they are:

· Turnovers should be a major focus: Many of Indiana’s failures last season were blamed on turnovers. This was not unjustified. The Hoosiers ranked 330th nationally in turnover percentage, last in the Big Ten and last among teams in a BCS conference.

Interestingly, something not many are talking about is Indiana has been average at best in this department for the last six years. Here’s Indiana’s turnover percentage and Big Ten rank for conference games over the last six years:

Data dive: A look at IU’s second half struggles

ITHUM0016

Editor’s note: Only conference games were considered in this analysis.

One of the topics covered earlier this year was Indiana’s propensity for close games and their struggles to win those games. Not only has Indiana played in a lot of tight games this year, it’s actually held a lead in many of them. In fact, only Wisconsin (14) and Iowa (13) have held more halftime leads than Indiana (10) in the entire conference.

Indiana didn’t hold a halftime lead in any of its first five Big Ten games, which means that IU has been the halftime leader in 10 out of their final 13 conference games. The caveat, however, is that the Hoosiers have struggled to hold onto the lead in those contests.

The chart below shows each Big Ten team’s winning percentage in the games it was leading at halftime:

Data dive: What wins in close games?

JSP_2216

One of the harsh realities of Indiana’s season thus far is that, in so many games, they’ve been really close. How close? Six of their eight Big Ten losses have been by seven or less points and the average margin of defeat in these games is just 4.5 points.

Only three of Indiana’s 13 Big Ten games have not been “close”. (For the duration of this article a “close” game indicates that the score difference was five points or less at some point in the final five minutes of the game.) Only Ohio State and Minnesota have played in more close games than Indiana this season and each has a better winning percentage than the Hoosiers. Though no program deals in “could-haves,” the reality is that the season might have a much different feel if IU had closed out some of these tight games, particularly in conference play.

Here’s a look at how each Big Ten team has fared in close games for both the conference season and the non-conference season:

It is no surprise that the teams at the top of the conference standings — Michigan, Michigan State, and Wisconsin — are some of the best in the league at winning close games. Likewise, teams like Indiana, Illinois, and Penn State have had trouble converting these close games into wins and find themselves looking up in the standings.

So what exactly are the good teams doing that the others are not?

Big Ten Geeks on IU’s rim defense

Big Ten Geeks: Getting Defensive

Indiana is allowing a ton of looks at the rim, but the Hoosiers rank ninth in the nation in defensive effective field goal percentage. How can that be? You guessed it–shot-blocking.

Indiana is tops in the conference when it comes to blocking shots at the rim, which is part of how the Hoosiers have allowed a ridiculously low 46 percent field goal percentage at the rim. Still, even taking out the blocks, Indiana opponents have shot only 55 percent on unblocked shots at the rim, which is also the lowest figure in the conference.

That can be partially explained by Indiana’s shot-blocking prowess–after all, good shot blockers alter shots even when they don’t block them–but there also seems to be some good fortune and/or strength-of-schedule effects at work. It will be interesting going forward to see if Indiana can continue to stop opponents while allowing them so many dunk and layup attempts.

Given these numbers and the low 27.8 percent three-point shooting of Hoosier opponents, I’m not completely sold that this is a top 25 defense like KenPom’s adjusted defensive efficiency says it is. It seems that reversion to the mean could be biting Indiana’s defense in the near future. On a team that will have to rely on defense to grind out an NCAA tournament bid, that’s troubling.

The decline of Indiana’s offense

There’s been plenty of conversation in the days following Indiana’s loss to Syracuse on just what went wrong. Some blamed the coaching. Poor preparation against the zone, they said. Others blamed the players. After all, the coaching staff wasn’t out there missing all those shots and turning the ball over. The Hoosiers were bested by a lengthy, athletic team playing a terrific zone they’d never seen before. They admitted to overthinking things on the court — which only compounded the problem.

Yet, a closer inspection of Indiana’s numbers reveal this: Its offense, the most efficient in the nation heading into the tournament, was nothing more than average, if that, in the month of March.

A look:

Month OPPP DPPP eFG% 3p% Avg. Possessions
November (7 games) 1.265 .816 58.0 41.2 70.4
December (7 games) 1.214 .864 57.0 41.7 73.7
January (7 games) 1.162 .948 55.2 44.3 65.4
February (7 games) 1.185 1.018 56.6 43.4 64.9
March (8 games) 1.029 .981 47.6 31.5 64.4
March (minus JMU, 7 games) .987 .978 45.7 29.9 64.7

Striking JMU from consideration — a contest the Hoosiers scored 1.35 points per possession against a team with a talent level more on par with a November opponent than a March one — Indiana scored less than a point per possession in its other seven games. And its shooting absolutely fell off the table. The Hoosiers shot over 40 percent from 3-point range in November, December, January and February. But in March — whether we include the JMU game or not — Indiana shot around only 30 percent from distance.

Big Ten Geeks on IU’s 3-point shooting

Big Ten Geeks on IU’s 3-point shooting:

The Hoosiers are, predictably, shooting worse than last season, but not by much. Indiana is hitting 40 percent from deep, maintaining the three-point shot as a very valuable weapon. Note that the team average would be 36.5 percent were it not for Remy Abell’s 10 for 12 performance. I thought Matt Roth had graduated, but maybe he’s just wearing a Remy Abell costume. In all seriousness, Abell’s return to earth should coincide with improvement from others who have shot worse than their ability (Victor Oladipo, Will Sheehey), so we shouldn’t expect a huge drop in team accuracy.

It’s still a bit surprising to see Indiana taking so many more threes than last season … Indiana has gone from reluctant to willing when it comes to hoisting three-point shots, and it seems unlikely now that the Hoosiers will fully revert to last season’s tendencies. This team is open to taking threes, which is very smart when you’re making 40 percent of them.

Indiana vs. the Big Ten: Team stats

The Big Ten season starts in less than a month. Every men’s basketball team has played at least six games; seven have played either seven or eight games. That puts more than half the conference at or near the quarter turn of the regular season.

With this in mind, a look at where Indiana is stacking up in a host of statistical categories vs. its Big Ten foes through Sunday’s games. It’s a little early to draw any grand conclusions just yet from all this, but from available non-conference data at present, here’s a look:

Team Adjusted Offensive Efficiency National Ranking Big Ten Ranking
Indiana 121.5 1 1
Michigan 117.4 3 2
Ohio State 115.4 7 3
Wisconsin 114.1 10 4
Minnesota 112.9 13 5
Illinois 109.2 33 6
Michigan State 108.3 39 7
Iowa 106.7 59 8
Purdue 105.4 74 9
Northwestern 103.1 106 10
Penn State 99.3 173 11
Nebraska 97.6 199 12

Despite a 5-3 record, Wisconsin sports the 10th best offense in the country and the 23rd best defense (see below). The Kohl Center is never an easy place to play — although one of the Badgers’ losses does come at home already this season (Virginia) — so it’ll be interesting to see what the team is able to do come conference time. And if you needed any further proof that the Big Ten is good, look no further than it having five of the top 13 offenses in the country.

Team Adjusted Defensive Efficiency National Ranking Big Ten Ranking
Indiana 86.4 5 1
Michigan St. 86.6 6 2
Ohio State 87.5 10 3
Minnesota 89.9 19 4
Wisconsin 90.0 23 5
Michigan 90.9 30 6
Purdue 91.5 34 7
Illinois 93.1 53 8
Iowa 94.7 74 9
Northwestern 94.9 77 10
Penn State 96.1 103 11
Nebraska 99.8 186 12

Michigan State’s defense — which finished third nationally last season — is back, just behind Indiana’s and good for sixth in the country. With a 13th ranked offense and 19th ranked defense, Minnesota is looking like it could make some noise once Big Ten season hits. Michigan is getting a lot of deserved buzz of late for their strong start after some thought they were ranked a bit too high to start the year. While their offense has been crazy efficient (third in the nation), a 30th ranked defense has room to improve. Penn State and Nebraska? Well, neither team is very good.
