Count me in with the "I don't see how BJack's overrated" group - I'd say he's the opposite and needs to be given more reps. Which leads me to...
Grant - he's got the tools, but seemed to get really soft last year. I'm willing to chalk it up to the hammy if he gets back to running angry again this year, but he looked like a very different back to me last year.
Jolly - Sure seemed to disappear last season, and the off-field stuff has to be taken into account - you can't be a top player if you're not on the field because you were suspended for being an idiot.
Harrell - This kid can't get on the field, let alone stay on it. His back needs to be ALL BETTER this year and I need to see him play the game. I'm hesitant to even call him "overrated" because his game's still such a mystery, but given where he was drafted the term fits (and will be replaced with "bust" if he doesn't show something in '09).
Daryn C seems to possibly be overrated by our FO and coaching staff, but he's certainly not overrated by the fans, most of whom seem to hate the guy. All I know is he's been less than impressive as a guard when I've seen him play that position.
