New to this site, hope yore doing well.
I like Blount going forward, but keep in mind two things...
Pats will look to keep Manning off the field, as he has been struggling and that's the best way to keep him out of sync. They're also at home and the Colts are 4th to last in rush defense.
Niners, on the other hand, are 8th against the rush, they are at home coming off an inspired win, they've got some momentum now with Troy Smith, they're at home AGAIN, so they've been well-rested.
I DO think Blount is the better back, but BenJarvus does it all right now and Blount doesn't play on passing downs...so I don't see him being used as a decoy and then suddenly the Bucs are running draw plays or delays, ya know?
I'd go with BenJarvus...stirictly a matchup thing...
