Still think a Tyreek Hill for George Pickens trade might work for all parties. Steelers get a big time weapon to team with their other offseason addition, DK Metcalf. Would be the most dangerous duo in the league.
Dolphins get the younger talent, more in line with Tua and Waddle. Lose speed, but gain a another bigger target with a big catch radius. Miami's wr corp would be Waddle, Pickens, Malik Washington, Westbrook-Ikina and two others from the pool of Eskridge, Ezukanma, Tahj Washington, Armstrong, Wease and Baldwin.
I'm all for keeping Hill, but if Miami does trade him I would prefer a move like this more than one for a draft pick. Also, if Pickens leaves as a free agent down the line, the comp pick might be greater than the pick you would have got from trading Hill.
