The first thing Al McGuire taught Tom Crean when Crean took over at Marquette was not to worry about competing against the past. “He told me, ‘You don’t have to worry about matching up with what I did,’” Crean said. That was why he came to know Rick Majerus, whose passing so moved him over the weekend. That also freed him up, and enabled him to honor the past while creating a present. He has the same job here now, with a team that might just be good enough to do it, and you can’t help but wonder why history has to be such a burden. There are blessings to it as well, if you just know where to look.
