It's an interesting scenario for sure.
Could argue that with Purdy's massive extension coming up, getting a ton of future draft capital to keep talent around him becomes very very important. Sure, would be a huge hit to this window here, but if we truly believe Purdy is a top 5/10 guy, then the window is basically always open.
But then, on the flip side of that, Aiyuk is at the very worst like the 10th best WR in football and showed incredible chemistry with Purdy. Those guys don't grow on trees. If he doesn't want to be here though or is pissed, what sort of value is that bringing in the locker room and on the field?
Happy Aiyuk is a no-brainer to keep around. Problem is, I wonder if the relationship is beyond that at this point.
