Kemba Walker recently returned to UConn after playing at the NBA summer league in Las Vegas.

Walker has participated in workouts with Omar Calhoun, a 6-foot-3, 190 pound guard who is the top rated player in UConn's 2012 recruiting class.

“You can tell that he works very hard and pushes himself,” Walker said in his assessment of Calhoun. “It's all up to him. If he keeps working hard, he can become a lot better."

Walker expects Calhoun to quickly adjust to the physical demands of college basketball.

"Physically, definitely, he's further along," Walker said. "That's huge at the college level.”
