The 22-year-old told NFL Network: "I've already made a giant leap, coming from a spread system where the biggest transition for me is going to be the footwork.
"It's not as if I can't do it, it's the fact that I haven't done it enough. The good amount of reps that I got in rookie camp, minicamp, OTAs has helped me make that leap and transition, and make giant strides.
"I have an opportunity to fight for a starting job in a great place right now, so I look forward to it."
The Jets start the 2013 season at home to the Tampa Bay Buccaneers.
