Video: Derek Fisher and Robin Lopez Mix It Up in Game 3
You know how these things go, right?
The initial contact seemed to be legitimately harmless, but it's hard to believe Lopez didn't have any intent when he connected (with his arms raised) with Fisher's head as he ran by afterward. That probably was neither an accident nor a coincidence.
No personal fouls were assessed, but the referees did dole out the dreaded double technical fouls, since they couldn't seem to determine that either player was at fault here. While I do believe that (despite the video not showing it) Lopez's hit to Fisher's head was at least a little bit intentional, the fact that Fisher ran at him from behind to address the situation is an act of aggression on the basketball court that could lead to a more serious escalation of a minor incident, and thus cannot be condoned.
The dueling technicals were apparently enough to put an end to any lingering hard feelings, as that was the last we saw of any physical altercations for the remainder of the game.
