Just watched the game replay on ESPN, and I didn't realize just how long the on-court, pre-fan "fight" lasted. Artest laid on the table for a long time...maybe two minutes, while the teams pushed and yelled at each other. Reggie Miller was by Artest, tapping him on the chest and making sure he stayed on the table and didn't get up. They had time to show the play, stay on the pushing for a good while, show a slo-mo replay of the foul, and push, and start of the pushing on court, then cut back to live action, then cut back and forth from Artest on the table to Ben pissed off, another 15 seconds or so, then the cup flew and hit Artest in the face, and all hell broke loose.
Watching the length of time it took for that to play out, I'm more solidly behind Artest in this debacle. He was clearly trying to manage his anger (which he has a problem with) and did so for quite some time. The cup of beer in the face was the proverbial straw that broke the camel's back.
