That's also just his opinion. I don't know if Zay will be on the 53 or not. These WR's are making it tough as far as coaches decisions on who to keep. Could I see them possible attempting to trade Zay? Yes, if they could get anything, but I'm not sure they could.
I can also see them possibly cutting him, and of course he could still make the 53. We don't know yet, but we will soon enough. However IMO I would rather have Duke make it before Zay all day long. But that's just me.
