Him playing RT is a non-starter. His connection with that position is tied to his dad (RIP) and he's been adamant about playing LT.
I'd take him at at that price for LT (max), but that's less than what he's turned down, and I don't think he's worth more. Perhaps he can be had if the guarantees are higher than his original offer.
I think Poles really wants to pick young guys in the draft that can be molded from day 1, which is fine, hopefully he finds the right guys in the draft, otherwise, missing out in FA will bite him in the ass.
