Luke Joeckel has said that he is keen on using his hands more when tackling and blocking in the NFL.
The Jacksonville Jaguars offensive tackle will play in the league for the first time this season, having been the second overall pick in April's draft.
The 21-year-old told the team's official website: "It's going pretty good, but there are definitely some habits I need to break.
"Defenders use their hands so much better here. They're better at their craft. To be able to block the guys I'm going against, it's something I need to learn how to do. I have to learn every trick to block those guys.
"Getting my feet there is one of the biggest things, but just as big is hand placement, being able to play games with them and not giving them the same punch every time."
Joeckel spent his last season in college protecting Texas A&M quarterback Johnny Manziel, who went on to win last year's Heisman Trophy.
