VIDEO: Warriors' Barnes hurts the rim with pair of angry crams

Maybe Harrison Barnes is taking out his frustration for not getting a contract extension.

Or maybe he only knows how to dunk one way - with unrelenting aggression.

Either way, the fourth-year forward slammed home a pair of beauties against the Phoenix Suns on Friday.

Exhibit A - this one-handed flush over helpless Suns defenders.

Exhibit B - a two-handed follow-up jam off a teammate's miss.
