Upgrading WR

RB: Alvin Kamar, Dalvin Cook - bunch of backups
WR: Godwin, Watkings, Diggs, Williams, Samuel, McLaurin, Robinson
TE: Kittle

I am thinking of offering Diggs for Mark Andrews. Team that has him also has Engram. My plan would then be to flip Andrews or Kittle for a better WR or 3rd stud RB.

Thoughts? To cute? not worth it?
