I agree with this, for the most part. An NBA game isn't over until the whistle blows. You have to keep scoring to win. Even still, the Thunder needed a whole lot to happen, so I don't think it was too big of a deal for LA to slow it down and milk the clock. An offensive foul on a screen and a turnover at mid-court are things that you can't do in that situation. If you are going to run clock, you can't turn the ball over like that.
Regarding the "controversial" calls:
1) The reggie jackson play was as clear a foul as they come. The refs screwed up big-time by not calling it, and I think that is part of the reason they didn't overturn possession. They knew they screwed up, and someone was going to be mad either way, so why overturn the original call? Rivers can whine all he wants, but his guy got away with an obvious foul. If the refs had called it right, Jackson would have tied it up on the line anyway. The refs just gave the Clips another chance to get a stop and win the game, but Chris Paul blew that chance.
2) Chris Paul's 3-pt foul. You can't bump a jump-shooters elbow and ***** about it being a ticky-tack call. If the refs see it, they call it every time. Sometimes they don't see it, but that's a different story. Paul gambled, and it was stupid on his part to do so. Seemed pretty clear that he bumped the elbow, so don't blame the refs for making the call.
