My opinion is that we need to draft a RB on the first two days of the draft next year. Wether you think Dixon is the future or not, we need to get another RB to complement him or take the lead role. I don't believe West is a consistent enough threat to carry our offense, and Woodhead won't be here long.
I personally would love to have Quenton Nelson in the first round (because he's an extraordinarily good prospect that would make our OL terrific and Roman would make a misery out of opponents' front with him and Stanley on the left side) so that would leave us choosing on Day 2. Prospects that have caught my attention are Akrum Wadley (not really a secret now), Damien Harris and Nick Chubb.
Chubb, provided he regains some of his lost explosiveness, is the incarnation of a workhorse, a guy you can eaily feed 25+ carries and who will hurt and tire the defense, while also being able to break a long one on any given carry. He isn't a perfect prospect even if he comes back more explosive, as his pass catching and protection ability leave something to be desired.
Wadley and Harris are more speed backs that can still absorb hits and take a lot of touches. I see them as Kamara like weapons. While Harris is the more athletic and faster back, Wadley has better vision, patience and agility to make people miss. He is a nightmare in the open field. If you believe one of West or Dixon can be the workhorse and carry the load, one of these two can be 15+ touches players behind them and will consistently exploit holes in the trenches or screens or dumpoffs and when they do, they'll consistently turn upfield for first downs and more.
Other RB that I like but still need to be convinced are Scarbrough and Ronald Jones. Jones is pretty great but can he take the pounding? He looks very slim for a RB. Scarbrough is honestly nothing really special imo, I like the violence that he runs with but he doesn't have burst or explosiveness in his lower body to wow you. He's stiff and won't make a lot of players miss.
