I don't know if you've got it sorted out yet but what I would do personally is...
Keep Bell and Tate
or
trade Mccoy for Freeman and Kelce, keep Freeman, (Kelce or Tate), & Bell
I've always been told not to keep QB's, I know Ryan is great keeper value especially in the 16th rd, but remember when he's had different or 1st yr OC's he's struggled.
Round 2 shoot for Michael Thomas, TY Hilton or Jordy Nelson
I do think that 2nd trade is a little one sided and not in your favor, giving up a 2nd rounder isnt ideal
Marshall could be a steal in the 6th but that's up to you, I have a bad feeling about him
Maybe you can help me?
