The fan was interviewed by KSL. He said he was taunting Westbrook about icing his knees. Westbrook shot back that it was heat, not ice. According to the fan, he then said some snide remark about the heat packs and Westbrook just went off. I'm not defending Jazz fans (I remember being at a game where they booed Toolson — a member of their own team — because he was a BYU alum) but Westbrook appears to have taken it too far.
