I honestly dont like either. Mathews bc of injury and fumble issues, and Hyde bc i dont think we need a #1 type back.
I think West is good enough to be the lead back, as your early down, between the tackles type runner. Then Woodhead gives us a 3rd down/receiving specialist.
What i think we need, if anything, is the change of pace/all around type back thats in between what we have in West and Woodhead. Decent runner that can play early downs, go between the tackles or bounce outside, while also being a good receiver.... but probably a guy you wouldnt really want toting the load, but can be effective in limited touches.
For that reason i think Forte really fits. Excellent all around skill set, but because hes aging probably isnt a guy you want getting 20+ touches. But to spell West for a series here or there, or for the 4 minute offense where you can still afford the run the ball, so you want someone that keeps the entire playbook open.... Forte could be a great weapon.
