First off, I'm not posting this to start an argument about Pat Fitzgerald. Divided as some of us may be, this has absolutely NOTHING to do with his abilities as a head football coach.
However, I feel that this tweet should be noted. Fitz is the face of the program (and the university in some cases) and this tweet did come off as ignorant and reminiscent of Gregg Easterbrook (an unfortunate recipient of a Masters from Medill). It obviously depends on how you read into the comment, but it certainly seemed racially charged to an extent. Watson points out that Fitz has said nothing of Derrick Rose, a Chicago product who has done nothing wrong on or off the court since coming to the NBA (or any other basketball player for that matter). Considering inner city kids make up a large part of the pool of heavily recruited NCAA football players--many of whom are very active on Twitter--this comment isn't smart.
He took it down and this is not going to have a big impact. But for a coach who consistently gets praised for the image he portrays of himself and the institution he works for, this came as a surprise.
