Trade for Gurley?

I’m locked into playoffs right now and Gurley owner is currently tied for last playoff spot, and will likely need to win 1 or 2 more to get in. With Gurley on bye, wondering if I should throw out an offer (or stick with what I’ve got). If so, what do you think would be a good offer that could get him without significantly weakening me?

QB: Fitzpatrick (replacing on waiver wire)
RB: Kamara, CMC, Mack, Kerryon, Duke Johnson
WR: Evans, K Allen, Sanders, Fitzgerald, MVS
TE: Njoku, Howard (dropping for someone on waivers)
DST: Chargers
K: Gano

12 team, 1/2 PPR, QB/2RB/2WR/FLX/TE/DST/K
