Robert Griffin III remains highly confident in his abilities after two difficult seasons to follow-up his Rookie of the Year campaign.

"I feel like I'm the best quarterback in the league, and I have to go out and show that," Griffin said. "Any athlete at any level, if they concede to someone else, they're not a top competitor, they're not trying to be the best that they can be.

"There's guys in this league that have done way more than me. But I still view myself as the best because that's what I work toward every single day."

In 2013, Griffin was returning from multiple torn ligaments in his knee but played the first 13 games before being removed from the lineup. Last season he dislocated his left ankle in Week 2 and missed six games.
