Voted Bell.

Hurst comes into arguably the weakest position group on the team, and you can easily let go of Smith or Wilcox to make room for him.

Bell would probably be the most impactful though, but safety might be the best position group out of SAF, TE, and RB. Scott would have to be the one to go if they make this move though, obviously.

Perine I think offers the least value, but he's the cheapest contract to take on and you could get rid of Evans (or Williams) if you bring him back.
Perine hasn't been good as a blocker for DEN, so I'm not really thinking there's a big upgrade in that department if he's back.

If I could go back in time to the offseason knowing what I know now, I'd have kept Bell instead of signing Scott, and I would have drafted Mayer or LaPorta instead of Murphy.
