Splitter played great D in the second half, and that was definitely a part of the Spurs gaining separation. However, I think it needs to be understood that D'Antoni probably cost himself his job by not having his two bigs - the engines of his offense - play their strong game which is posting up down low. So with the coach running a gameplan which is obviously detrimental, and not running his offense in the best way possible, having Splitter guard against their strongest offensive option is much less necessary. I'm quite stunned that D'Antoni could not figure out the obvious as an NBA head coach.
