Terrelle Pryor's progress this season has been one of the most entertaining storylines to follow.

He has almost single-handedly transformed the Oakland Raiders from a 2014 NFL Draft quarterback-lottery team into one that is intriguing to watch every week.

Yet, Pryor, who spent his bye week working on his footwork and mechanics, knows he needs to improve to show he can be the Raiders' quarterback of the future.

"There have been big improvements; I'm proud of my work," he told NFL Media's Albert Breer earlier this week. "And I have confidence that if I continue to work hard, I'm gonna get where I wanna be -- and I wanna be one of the best. ... I know I can do things other people can't."

He's got that last part right. His athleticism is breathtaking.

Unfortunately, his mechanics have also left evaluators gagging.
