Mistake? Probably, but I don't think how big of a mistake. I wanted to Sessions to start, so I can't hang that on Mike Brown. But in hindsight, I can see a scenario where Sessions would be great off the bench. From a basketball standpoint his game would have been freed up in the 2nd unit.
But did benching/starting Sessions determine:
-Whether we lose or win against OKC: No. Putting Sessions in the 2nd unit wouldn't change the outcome of the games. We lost some close ones to OKC, but Dallas lost the same kind of close games and they were swept. 4-1 and 4-0 isn't that much different. It's easy to say "if only we had done this or that...", but the games played out. OKC beat us in 4 out of 5 games. If that doesn't prove OKC were a better team than us last year, I don't know what will. The best team always wins in a 7 game series.
-Whether Sessions opts in instead of out: No. Not at all.
So in the end I think it's inconsequential.
