Kendrick Perkins learns basketball from Scott Brooks

Kendrick Perkins is a big guy. But size isn't power. Knowledge is power. (OK, so maybe when you're a 6-11, 270-pound center like Perkins, size is power, too.)

Every day, Oklahoma City Thunder coach Scott Brooks gets to teach Perkins some of his knowledge.

Perkins has been in the NBA for nine years — he declared for the draft out of high school — and become one of the NBA's toughest post defenders in the process. But he's always learning. And he appreciates his teachers. Just watch this reaction to a little coaching from Brooks during Thursday's game against the San Antonio Spurs:

Keep learning, Perkins.

Also, reading is fundamental.
