Here are last year's ratings.
Here's my take on a few.
MJD is already at 95 - I see him holding, maybe even going up a point or two, but I see his speed rating going down also from a 94 to maybe 90 or so. He's already said he's going to work on that this year.
Gabbert was rated 75 - I think he drops to high 60's. His accuracy definitely will drop from 83 waaay down. Awareness is already low at 50. It probably won't move a whole lot... But I think there's some sort of potential metric in the game and I think if anyone starts a franchise and is patient with him they could develop him into a good player over a few seasons. He will probably be the only QB on our roster to go from 2011 to 2012.
Marcedes will drop from 90 for sure. I'm guessing below 85.
I doubt the draft will help much, as rookies always start pretty low. (Deservedly) But if we can get a couple FA WR's, playing the Jags as your team might not be too incredibly difficult.
