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.
