The Spurs won because they played Miami, plain and simple.
And I for one think it's great that Eddie Jones got what has been coming to him. When you spend years on the Lakers roster and on the Charlotte roster never proving yourself in crunch time or in the playoffs when it matters most, it tends to come back and bite you a bit. He is a medicore performer at the most and I can guarantee you that Miami won't be his last team. They too will soon tire of paying him as much as he makes and only getting average 2 guard play in return.
He has been one of the most overrated players in the NBA. He has consistently managed to get himself hurt or somehow disappeared during every playoff run he has been a part of thus far in his alckluster career. I'm never been impressed with him (yes, even when he was a member of the Lakers) and have yet to really see why everyone has had their tongue so far up his butt all these years.
Perhaps it's because he was the Lakers highest pick since Worthy and we felt we had to love him, I don't know. Perhaps it's because he, um, because he, well I can't really think of too much more he did for the organization. In fact as soon as we dumped him for an equally average player in Glen Rice, the Lakers pulled their first trophy down.
All that being said, San Antonio got a lucky draw playing Miami as their first game without Duncan. Come Thursday, their luck changes sides, drastically.
