Derrick Williams is heading to the NBA after his sophomore season.

"After careful consideration and with the support of my family and Coach Miller, I have decided to declare for the 2011 NBA Draft," said Williams. "I have enjoyed my two years at Arizona both on and off the court. I want to thank my teammates, who are like brothers to me, my coaches and all Wildcat Fans for making my experience an unforgettable one."

In two seasons at Arizona, Williams averaged 17.8 points, 7.7 rebounds and 0.8 steals per game in 69 career appearances (68 starts). He connected on 58.6 percent of his field goal attempts (388-of-662) in that span, a figure that ranks fourth on the UA career field goal percentage list.

The 6-foot-8 forward has been projected as a top-3 pick.
