Johnson, out of Fayetteville (GA) Fayette County, chose Clemson over LSU, UNLV and Florida International.

“When they sat me down on my visit, they showed me how much I can do for them,” Johnson told ESPN.com. “I know I can help them at the two, three and even the one.”

Clemson lost senior guard K.C. Rivers and sophomore guard Terrence Oglesby, who left to play in Europe.

Johnson left Southern Cal after the program came under scrutiny from the NCAA because of the O.J. Mayo scandal. Head coach Tim Floyd later stepped down.

“After that happened, I wanted to get out,” Johnson told ESPN.com.

TOP TWEETS & BLOGS FROM NBA CAMP

How has the departure of John Calipari from Memphis to Kentucky impacted you?

It hasn’t really. He’s a good coach. I don’t know if I like the way they’re doing things right there now though. Seems like he left Memphis kind of in a bad situation and then guys at Kentucky are getting their scholarships taken back. I don’t know yet. It’s a competitive place though, you know college basketball, and it’s only getting more and more competitive.

–In a star-studded affair, Michael Gilchrist of Elizabeth (N.J.) St. Patrick (pictured courtesy Courier-Journal) battled Barnes in the first game.
