jay cutler is what we all hoped that rex grossman would be. i'd say as far as arm strength, cutler has a slight edge although rex has a monster arm as well. the two key differences are 1. cutler's legs, he is as fast as any qb not named vick, and 2. his pocket awareness, which is probably more important. for example, on knox's 59 yard catch, cutler does what rex did not, he stepped up. rex would have tip-toed back and either gotten hit hard, or tossed up an incompletion or an INT. 3. he also doesn't get those wide, koala bear-eyes and he's not afraid to go up to his line and give them an earful, subjegating kreutz, who has routinely dominated his quarterbacks. in short, he knows how to handle the veteran red-assed center and that's super important.
