I think that may actually be a CB6 battle. White, Wallace, T. Johnson, K. Johnson, and now Neal appears to be a full time CB. Maybe they don't keep 6, but it's definitely one of the most heated battles right now.
Also, I feel the RB4 battle is heavily in Perry's favor right now. I think he becomes a core ST player this year, especially if they decide to not keep Pitts.
And don't count out M. Alexander (EDIT: for LB6/core ST).
