Basically, he'll earn a lot of the "pay cut" back - unless he is injured again
On Wednesday morning, ESPN's Mike Rodak reported that the base salary for Buffalo Bills defensive tackle Kyle Williams had been reduced from $6 million to $4.25 million for the 2016 season, saving the Bills $1.75 million against the salary cap.
Mike Florio of Pro Football Talk supplemented that report on Wednesday evening with this wrinkle: Williams can earn back all of that $1.75 million through playing-time incentives, and that those incentives start to kick in at the 35 percent of snaps threshold.
