Haven't been on here for a bit and thought maybe it was just me watching Diggs, clearly avoid contact. I'm sure if he's the only one in the vicinity he attempts, but he's not actively sticking his head in there.
I'm not itching to trade him but I would definitely listen... In the salary cap era you can't have $15M players all over your roster. You have to decide on your team identity. You can't have QB, WR, RB, 5 OLINE, TE, DE, DT, CB... all be all pros. Do you want CB's or pass rushers, is often the choice. In the past I was a huge cover CB fan, but I don't think Diggs is a huge cover corner. He's more of a turnover corner and I'd spend that extra $10M on pass rush.
Diggs isn't Deion, not even close, and he gambles far to much for my liking. He's obviously a great CB, but get's burnt... badly at times. It's all your teams philosophy but I'd rather have less turnovers and see more catches prevented. That could be a cheaper CB and I would invest that savings in my team identity which would be QB, Oline, WR and pass rush.
