David Wilson has said that he has learnt more of the New York Giants' offense ahead of the 2013 NFL season.

The running back is expected to take on an increased role with the team in his second season in the league.

The 22-year-old told reporters: "It's just that I know more of the offense this year and I can be more effective that way because I know if I'm asked to do something, I can do it.

"Last year I had limitations on not knowing certain things and not being able to react on the fly when certain opportunities were presented. Just having a year under my belt makes me more knowledgeable about the game.

"It's more so a mental thing because there was a lot more thrown at me and there was a lot more I had to learn. My mind was tying up my feet sometimes."

Wilson had 71 carries for 358 rushing yards and four touchdowns last season.
