The Buffalo Bills have a wealth of resources to work with in order to shore up their roster this offseason. It appears they have now managed to clear up even more cap space by restructuring the contract of defensive tackle Star Lotulelei.

According to ESPN's Field Yates, Lotulelei's base salary will drop by $1.75 million and instead be converted into guaranteed money:

Lotulelei was a former first-round pick by the Carolina Panthers back in the 2013 NFL Draft. Once his rookie contract expired with Carolina, he signed a five-year deal worth $50 million with Buffalo prior to the 2018 campaign. He has since established himself as the anchor of the defense up front following the retirement of defensive tackle Kyle Williams.

General manager Brandon Beane has done a steller job of taking advantage of whatever loopholes he can to make more room. As a result, Buffalo now has upwards of $80 million in cap space heading into the offseason.

Although the Bills have managed to clear up plenty of space, most of the money will likely be tied to the looming contract extensions of several of their key players. Quarterback Josh Allen will soon be eligible to for a long-term deal. Cornerback Tre'Davious White has also established himself as one of the NFL's premier shutdown options and is looking to get paid as such. Meanwhile, linebackers Matt Milano and Tremaine Edmunds are also looking for a lucrative pay day.

Fortunately, Beane has already started to take precautions by restructuring Star Lotulelei's contract without actually forcing hi to take a pay cut.
