If the Bills assign the franchise tag to Hughes, they'll have nearly $50 million of their salary cap devoted to him and his three Pro Bowl counterparts on the defensive line: Mario Williams, Kyle Williams and Marcell Dareus. Whaley has stated the Bills can absorb a higher cost on their defensive line because of their low quarterback spending. Tagging Hughes, however, would cut the Bills' 2015 salary cap space in half, potentially making them less active on the free-agent market.
