I see how you try to twist things into making it seem like gasols fault. This game was on Kobe. Just because he made a few shots in the fourth, it doesn't make up for his lack of discipline on defense and his careless turnovers.
He had careless turnovers and some bad defensive possessions, but they didn't kill us as badly as Gasol who doesn't care to play a lick of defense. 18-7 run flipped a 9 point advantage to a 2 point deficit. That run consisted of drives by Wall and Ariza, collapsing defense due to the lack of a reliable anchor, and various kick-out after the collapse. That's going to hurt especially bad when John Wall is the one attacking us off the dribble.
Kobe got burned on a few possessions by losing sight of his man, not going to deny that, but the majority of them were due to giving help on the drive because Wall was penetrating at will off the high P&R. The high P&R in general destroyed us when they dragged either Jamison/MWP/Gasol up to cover, since Nash has no chance of containing Wall off the dribble. As a result, our defense falls apart, Kobe can't recover quickly enough to his man, and we get smacked around by the same play over and over.
The catalyst was Pau Gasol's time on the floor to close the 3rd and start the 4th. It carried over the rest of the game once the Wizards realized that dragging out anyone but Howard off the high P&R was the key to destroying us. Once Wall got into rhythm and found confidence late in the game, it was essentially over. We gave up too much momentum with that stretch that Howard rested. There is no way to contain John Wall off the dribble if we have such horrible man coverage with Nash and equally bad help coverage from the likes of MWP/Jamison/Gasol.
