who to cut?

[eltoo]

14 team, full PPR, auction league. Drafted this week, and did not draft a K or Def so have to cut 2 guys to pick up K/Def before the season starts.
Spent most of my budget on Antonio/Evans with the plan to figure out RB as the season goes, grabbed Deangelo to give me 3 weeks to see if any of my bench guys emerge.

Currently, I'm leaning towards dropping Crowell & Coleman. I'm bit of a Sharpe truther and want to have a WR on the bench for depth. I'd like to hang on to guys with the most upside/the weakest guys ahead of them on the depth chart. Crowell will probably get the most consistent carries of anyone on my bench, but I don't see much upside. I like Coleman, but Freeman is looking good.

Any thoughts? Thanks!
