Mario Addison
The first player on this list would be defensive end Mario Addison, who the Bills signed as a free agent last offseason. The signing last year made sense as the team wanted to improve their pass rush and adding a veteran like Addison should have been a boost.
He knows this defense well from his time with the Carolina Panthers and playing for Sean McDermott, who was defensive coordinator at the time. However, Addison finished the year with only five sacks and the Bills added a number of pass rushers this offseason like Greg Rousseau, Carlos Basham Jr., and Efe Obada.
When considering Addison has the fourth highest cap hit on the Buffalo Bills this season, along with the depth they now have at the position, making him available in an expansion draft would be a great move for this team, especially if he were selected.
