According to the Thursday salary cap report on the NFLPA website, the Pittsburgh Steelers have gained $2,392,500 in available space. In other words, that means a contract restructure was done.
By the looks of things, tackle Marcus Gilbert was the player the Steelers chose to restructure because dropping his 2016 base salary down to the minimum for his accrued years, $760,000, would result in his cap charge this year of $6,461,000 dropping by exactly $2,392,500. That required Gilbert being given $3.19 million of his scheduled $3.95 million base salary as a signing bonus.
