Bowers, 24, had one sack and two tackles last season while battling a knee injury. It was his third season since being a second-round pick by Tampa Bay in 2011.
Bowers admitted the injury wasn't the only factor in his play last season.
"It's not all about the injuries," he said. "I let other reasons get to me mentally. It was Schiano. He got to me mentally, and I couldn't bounce back for some reason. I blame myself though. I couldn't push through it mentally. It taught me something and I'm a better person and a better player because of that."
