Trading for DJ

I have a 12 team ppr league, am 6-1 and looking to get David Johnson. Wondering what I should offer for him.

QB: Smith, Mariota
RB: Zeke, Ingram, Hyde, Crowell
WR: AB, Michael Thomas, Tyreek Hill, Marvin Jones and John Brown
TE: Engram
D: Broncos

I wouldn’t offer much, if anything. There’s a good chance he doesn’t play the rest of this season, especially with Palmer’s injury. AZ would be wise not to rush him back in a lost season.

Thats kind of what I was thinking too. Im in a good place and have the depth.
