I know there is tons of talk about the officiating, even from the national media, but that was not what cost the Spurs the game. Sure it did not help and was definitely an advantage for OKC.
From what I saw, what really cost us the game was missed open shots in the second half. Duncan began hesitating on his looks from the top of the key and most times that he does this, he usually ends up missing. Compare that to the first half when Duncan was catching it and firing almost immediately and hitting. If the Spurs kept hitting their open shots, then they would have won. Heck, even if they had hit half of their open shots, they probably would have won because it would have put additional pressure on OKC and things would likely have played out differently. At that point, the officiating probably would not have mattered.
I will not lie, watching the officiating was aggravating and upsetting, but do not hold that against OKC. They are a great team and should be treated as such. Congratulations Thunder.
I look forward to seeing what the Spurs do in the off season and next year. I personally feel they will still be playing well next year and could go far in the playoffs.
