Johnson, ranked #28 nationally and the #8 power forward by TheInsiders.com, cancelled a scheduled visit to Georgia Tech to announce his intentions to play for Coach Pitino at U of L.
"Brian can post up," Oak Hill Head Coach Steve Smith said. "He's got a great game with his back to the basket but I like him because he's so versatile and can face the basket."
Though he's a strong interior player and an excellent rebounder, Johnson can also step out on the floor and knock in the mid range jump shot.
"He's got a great body and is a very highly skilled big man," Smith said. "He's a true power forward in college and if you need him to play center he can do that as well. [But] he can really shoot the ball and put it on the floor and he's a very good interior passer."
Johnson, who transferred from Bishop O'Connell in Arlington, Va to Oak Hill this season, averaged 16 points and 11 rebounds last season as a junior.
"He wanted to come here to get motivated and get himself ready for college next year," Smith said. "He's a great kid."
Johnson becomes the fourth player to commit to Louisville from the class of 2004, joining 6'10 center Terrance Farley, 6'7 small forward Donta Smith and 6'6 shooting guard Lorenzo Wade.
And Louisville doesn't appear done with this recruiting class just yet. 6'10 David Burgess will make an official visit to Louisville this weekend and Sebastian Telfair will likely announce his decision to join Coach Pitino program in the near future.
Johnson picked Louisville over Notre Dame, Georgia Tech, Cincinnati and Arizona.
