At least one AFC executive believes Rob Gronkowski won't be fully off the trade block until he signs an extension with the New England Patriots.

"Where's the restructure of his contract?" an AFC personnel executive told Boston Sports Journal's Greg A. Bedard. "Until that's done, I think he's still available. I wouldn't be surprised if (head coach Bill) Belichick is going to test Gronk's buy-in with the contract."

Gronkowski reportedly considered retirement this offseason.
