Tony Snell has said that he has been concentrating on improving his defensive play ahead of his first season in the NBA.
The small forward was selected by the Chicago Bulls with the 20th overall pick in this year's Draft.
The 21-year-old told the Bulls' website: "My main thing was defense. To me, defense wins games. I love playing defense. I'm just trying to get used to defense at this level, being in the spots I need to be, and helping my teammates.
"That was my main priority. My offense is going to come around, but I've got to be consistent with my defense. It's all of those things. It's definitely a matter of getting stronger, especially at this level.
"Guys are professionals and they play with a high IQ. So it's simple things like getting my legs stronger so I can be in a defensive stance more often, when you stand up, your reaction isn't as fast. I try to stay down in my stance in order to react quicker."
Snell averaged 10.5 points per game during the last college season.
