Not UDFAs they just picked up. I'm not saying UDFAs can't be valuable contributors, but counting on them to be your starter is asking for trouble.
RBs dont tend to get better so I dont understand your point here.
Sounds like you were proven wrong and you are equivocating.
What smart teams do is get a stable of backs and roll with it. I betcha the Titans will regret signing Henry of they do.
What I think is the best method is to have 3-4 backs at all times. Next offseason draft a guy to replace Drake. You still have Edmonds and probably Benjamin. Maybe the Ward makes the practice squad and he factors in.
Year after that you have a 2nd year back and if Edmonds comes back on a cheap deal for a few years, cool. If not, another cheap guy.
Rinse and repeat.
