Sometimes big players will still beat the double team. But they'd have had a better chance against him consistently double and eve triple teaming him.
5 of Rex's starts his stats were positively horrific. The media attention is richly deserved for those games, look at the number:
Ariz - 4 INTs, 2 fumbles, 10.2 rating
Mia - 3 INTs, 1 fumble, 36.8 rating (his best of the terrible games)
NE - 3, 1, 23.7
Min - 3, 0, 1.3
GB - 3, 1, 0
Those stats are a nighmare. The Pro Bowl voting is silly anyway (how in the hell does Merriman get in the Pro Bowl after being suspended for 4 of the 12 games that happen before selection is done?!) so that doesn't matter. But his inconsistency is very real, and when he's not playing well the Bears would be better off having pretty much any randomly selected member of the team lining up under center.
"...when he's not playing well the Bears would be better off having pretty much any randomly selected member of the team lining up under center." Don't be silly. I have seen pretty much that in the past. It is far uglier than anything Rex has done.
Even after posting horrible numbers in two of those games Rex brought the team back to win and in another it almost pulled out a victory. Grossman has shown the ability to come back from a decifit and a bad showing.
He has great potential and should be our leader for years to come. If allowed to become a free agent after this year Grossman will get huge offers from other teams.
