I'm still on the Peterman bandwagon... I think his ankle was hurt last year and he was basically a rookie, so he didn't have much chance. Mickey said the other day that he saw Peterman playing racketball and he couldn't believe how agile and quick Peterman looked. Even Mickey said he expected a big lumbering oaf, but Peterman surprised him with his athleticism.
Racketball definitely isn't football, but lack of athletic ability is what supposedly has held Peterman back... We already know he's tough, nasty, and a hard worker.
I wouldn't be surprised if he broke out like Bradie James or Jacques Reeves. Nobody expected much out of those guys, either, then suddenly they were contributors.
