PHOENIX -- By one measure, the Buffalo Bills have made Charles Clay the NFL's highest-paid tight end.

Clay received $24.5 million in guaranteed money in his new deal with the Bills, eclipsing the $24 million that Julius Thomas took home as part of his five-year deal with the Jacksonville Jaguars.

The Bills' deal with Clay will average $7.6 million per season, the fourth-highest among NFL tight ends behind Jimmy Graham ($10 million per season), Thomas ($9.2 million) and Rob Gronkowski ($9 million).

Clay has a relatively lower cap number this season ($5 million), which helps the Bills as they approach the NFL's spending limit. NFLPA records listed the Bills with $7.459 million in cap space Tuesday, the majority of which will be budgeted for rookies, in-season signings and other adjustments.
