Rex Ryan has said that he believes Mark Sanchez can improve as an NFL quarterback.

The 26-year-old is expected to face competition for his place in the New York Jets' starting lineup in 2013, following a dip in form in the 2012 season.

The Jets head coach told NFL.com: "Bringing in competition at every position, not just the quarterback position. That is what we want to do. So to say Mark Sanchez or this quarterback or that quarterback, I think there's clearly going to be competition.

"I always think a young player can improve, I don't think there is any doubt. I think if you look at Mark, what is he, 25, 26 years old, in the life of a quarterback, I don't believe that's over the hill by any stretch."

Sanchez threw 18 interceptions and was sacked 34 times during 2012.
