Which rookie would be best bait?

[JTAx]

Went heavy with rookie RBs this year. Figured they were good value. Should I try to move any or stand pat for now?

TD-6 league. Pass 1 for 50 +5 at 300. Run 1 for 20 +5 at 150.

Any thoughts. Thanks.

Starters in caps.

QB - RIVERS, Edwards
RB - PETERSON (Keeper), MORENO, Wells, Bradshaw, D Brown
WR - C JOHNSON, COLSTON, Ocho, Walter
TE - OLSEN, V Davis
K - GOULD
DEF - RAVENS, Jets
