While the overall numbers arent bad I do see two potential problems with this signing.
One, if Clay cant stay healthy thats a lot of money for a guy who cant stay on the field. His knee problems are a bit concerning.
Two, if Clay plays well the way this contract is structured encourages a holdout after year two. We've seen it a thousand times, the moment a guy feels like he isnt getting paid what he's worth it's trouble and players (and agents) tend to conviently forget that their contract was front loaded.
Granted, a restructuring next off season could fix problem two but Im wondering what Clay's motivation for restructuring would be when he is already guaranteed a huge payday that year.
Dont get me wrong, loke the Bills Clay was the guy I most wanted in FA, but the upfront and guaranteed money could come back to bite them. And before anyone says it, yeah, I realize the Bills needed to find a way of structuring the contract so the Phins couldnt match. However that doesnt mean it wont come back to bite them.
