I guess what I see here, is that if the rest of this game had been handled better with rotation, play-calling, match-ups, and post-break sets, that all this fast-and-furious substitution at the end of the game would not have been needed in the first place. These Cavs are not nearly as good a team as this series has made them seem, (we should have blown them out, seriously) and I feel a lack of consistency and expertise on the coaching end is the primary reason.
In order for a team, any team, to be their best, they have to be given the best tools, and be put in the best position, to win. Those tools come from their individual talents and abilities on one hand, and the on-floor combinations, plays called, and motivations from the coaching staff on the other. I honestly don't see that happening here in the playoffs, and it's obvious to me that the lack of consistency and sensibility, leaves these great players we have, scrambling to keep up with the confusion they're thrown into as a result.
