Allen Iverson and a dead friend serve as Dion's motivation, and the reason he wears number three.
At media day yesterday, Dion Waiters announced that he would be changing his number to three for the upcoming season. Last season, Waiters wore number 23 for the Thunder. Waiters would have worn number three last year, but it was already taken by Perry Jones. With Jones now in Boston, the number three is now free for Waiters' taking.
Dion Waiters wears number 3 because he idolized Allen Iverson while growing up in Philadelphia.
