What's the point of carrying Dunbar who can't pass block and isn't a great running threat at this point?
Sure, I'd love to pick up a bigger, younger back. Now name me that player that's going to be available.
Fred Jackson is likely going to be the best TB option out there. He's better than Dunbar. This isnt rocket science IMO.
Maybe the thinking with the coaching staff is that Dunbar could be used as a "Sproles" type? Do I think this also? Not really....but I do think he could be a versatile back that can go in motion and play the slot, be used in the screen and contribute on special teams. He may not be the traditional back you may be looking for, but I don't think anyone has that expectation of him. As far as his lack of production is concerned, the staff hasn't really utilized him much (which is frustrating).
Is Jackson going to contribute much in ST? I doubt it and the third running back needs to contribute there often and do it well.
As far as younger/ bigger backs, I'm keeping an eye on Terrell Watson from Cincy. Also from Cincy, James Wilder is another big back that intrigues me and although not younger/ bigger, Cedric Peerman who could also get cut is considered to be an excellent special teamer. He's their ST captain actually and was like 2nd in the league in ST tackles last year.
Juwan Thompson from Denver looks like a player to me. If by some miracle Montee beats him out, I'd gladly take a look at Thompson.
Not sure how things are going to play out in San Fran, but I'm keeping an eye on Mike Davis. Not a "big" back, but he's stocky and I think he can play.
And I'm not a big fan of Bryce Brown, but some on this board seems to like him.
