Trade Felix Jones for Percy Harvin?

[Fuqyu]

I'm in a standard non-PPR scoring league

my RBs: A. Peterson, Shonn Greene, Felix Jones, Mike Tolbert
WR: Dwayne Bowe, Calvin Johnson, Legedu Naanee, Brandon Gibson, the TB Mike Williams

Oh yeah, and I have to start 2 RB and 3 WR weekly, no flex position.
