From Rivals.com:

Barkley is already considered one of the greatest quarterbacks at a
high school that has produced two quarterbacks who won the Heisman
Trophy (John Huarte in 1961 and Leinart in 2004). But to those who know him best, it’s
neither stats nor awards that make Barkley the best player in the class
of 2009. It’s much more.

"He’s got the God-given arm strength, his vision is impeccable
and he has great instincts for the position," said Rollinson of his
star quarterback. "But it’s his passion for the game and his work ethic
that separates him. He studies so much film he even spent time with us
learning the pass protection schemes so he’d know where pressure was
coming from on each play. It’s the little things like that."

Barkley is accumulating honors at a fast clip. In addition to
the Rivals.com award, he was the first junior to win the Gatorade
Player of the Year award for football.

"I just love football," Barkley said. "I always wanted to be a
quarterback because I like the feeling of control I get with it. I like
to know where the ball is going all the time, that’s why I don’t like
defense at all. Defense is for a different kind of personality than
mine. I like the mental aspect of quarterback too, and love watching
film and being in the weight room. I like everything about it."

Definitely worth reading it all.
