First, let's get my biases out in the open: I'm a Bears fan, and a Grossman owner in dynasty. I'm hopeful that he'll be the guy for a long time in Chicago...but by no means do I think he's a lock for super-stardom. That said, here's what I think he's got going for him: first, Ron Turner's a good OC. Back in the late 90s, he fashioned the best Bears O many of us have ever seen -- with Erik Kramer, Curtis Conway, Jeff Graham, and Raymont Harris. Hardly studs. Of Grossman, Berrian, Muhammad, and Benson, I'd say only Berrian isn't quite as physically gifted as his late 90s counterpart, and that's close. The rest are all more talented, and I think Turner, with one more year coaching them all, makes it show. Second, he works hard, and doesn't pass the buck when he's the guy who screws up. For as bad as he looked at times last year, he's young, and willing to work to correct mistakes and improve himself. Third, he has the support of the team -- it's not just Lovie who thinks he's the man. The entire team, offense and defense, likes the kid. He's a natural leader.
My optimistic hope runs along these lines: he finished last year with 7 games with a passer rating over 100 (which is awesome) and 5 with a rating less than 40 (which is historically bad). He's playing an equally weak schedule in '07. With this schedule, and expected improvement for a young guy continuing in a solid system, I say we see "good Rex" as often as '06, while "bad Rex" becomes "mediocre Rex". Adding it all up, I think he's solidly top 10 (barring injury and all the usual disclaimers).
