I hate blaming refs, but that game seemed to be a tip job by the referees. The Lakers were in the bonus for a lot of the 4th, while the Mavs never got there. The refs missed the foul where Dirk got hit on a shot, and then the ref compounded things by teching him up.
On the Mayo call on the Kobe layup, not only was it a weak call by Ken Mauer (whom I refer to as Rat Face), some new jack ref was the one who rang up Mayo on the tech.
The refs also allowed Artest to WWE Dirk the entire fourth quarter.
