A good coach may argue some calls, but if in the end you spend more time arguing with officials your team tends to start believing the whole world is against them and they can not win. I think this was pretty evident the way they folded at the end. Even when they were only slightly behind and had a chance to go back on top he was still over by the officials complaining instead of focussing on the task at hand. And his team picked up on that and fell apart. Win with grace lose with grace, he certainly did not. Some of those calls were questionable, but his complaining impacted the game more than the calls.
