Despite criticism to the contrary, Rex Grossman can play.

I must preface this with a disclaimer:
I am, always have been, and always will be, a Chicago Bears fan. No matter what.
I just came across a column on cbssports.com which basically validates much my criticism of the Bears for some three years. Surprisingly, this comes from Pete Prisco whom, in my estimation, is no Chicago fan. But he does, apparently, understand that Lovie Smith and Ron Turner are less than fully capable of running a dynamic NFL offense.
Not to sound completely arrogant, but I had Tony Romo figured out a full week before opposing defenses determined his flaws. Granted, my initial response was "make him throw from the pocket," which is undoubtedly a simplistic gameplan. That is, however, just what happened the next week. But my point is the commentators, prognosticators and talking heads are often ignorant bandwagoneers.
Anyway, to my original premise: Rex Grossman can play. Many of his struggles can be blamed on lousy play-calling or an aged offensive line. Any quarterback, no matter how good, will struggle to make big passing plays in an obvious passing situation. And I can't count the number of times I saw Grossman sacked, on his back with three or four defensive players all over him while three offensive linemen were standing at the line of scrimmage, looking for someone to block.
I've maintained that if Grossman were in a system that played to his strengths, his live, accurate, very strong arm, he could be more successful. There are few quarterbacks who can throw as pretty a deep ball. Protect him in the pocket and just let him throw. I'm not so naive as to suggest, however, that Grossman is an elite quarterback. But, given the right circumstances, he possibly could be. He has the talent.
One last observation -- Grossman was pummelled for his tendency to throw interceptions. My theory is he threw recklessly at times because he could. He had a big arm and could make strong throws few other quarterbacks could. So he took chances.
As an aside, Jay Cutler, the big-time Pro Bowler for whom the Bears sold the farm, is a gunslinger as well. Just something to think about...
