Own D.Watson and R.Wilson, need to trade for a RB

12 team PPR league (7 keepers)

Only offer I have is Adrian Peterson. Any ideas? Deep at WR and draft picks are an option as well.

QB - Wilson/Watson
RB - Mixon/McFadden/Allen/Riddick/Charles/Perkins/Carson(IR)
WR - Nelson/Baldwin/Jeffery/Fuller/Davis/Golladay
TE - Henry/Howard
D/ST - Ravens
K - Butker

is your league PPR?

Yes, half PPR
