Blake Bortles admitted this week that his arm was far from 100 percent as his rookie season with the Jacksonville Jaguars progressed.

"My arm kind of deteriorated during the season," Bortles said at the start of Jacksonville's voluntary offseason conditioning program, according to ESPN.com. "It didn't affect anything. It was just, I think, a product of throwing for two years straight without any break.

"Took some time off, let it heal, and then went kind of (to seek) out some proper mechanics on how to make it never hurt again."

Bortles spent the first part of the offseason without a football in his hand, working on improving his mechanics. Bortles wanted to clean up his footwork and throwing motion while also losing weight.
