'In terms of what Clay will cost the Bills against the salary cap, the tight end carries a $5 million cap hit in 2015, $13.5 million cap hit in 2016 and cap hits of $6.5 million from 2017 through 2019. The Bills would be able to lower Clay's 2016 cap hit by converting his $10 million roster bonus into a signing bonus, which would spread the cap hit over the rest of the contract. Buffalo also included a no-trade clause for the first three seasons of Clay's deal.'
