Here's my interpretation of what happened last year:
CJ gets hurt late in the season, comes back after missing a bunch of games right before the season ends. He's fresh for the playoffs, and just kills it.
Meanwhile, no such Load Management for Lillard, who had to go Extra HAM as CJ AND Nurk were out. What happened? We went on an absolute tear, which continued into the OKC series. However, after that series, he was physically and mentally spent. We managed to win the playoff series, but he was basically done by the end.
We still put up a fight against GS - leading more minutes than them, but without a rested Lillard and without Nurk, we lost.
So, I'm OK with Load Management during the first 2/3 of the season, but we should seriously use it down the stretch - on everyone except Nurk! Being rested for the playoffs is extremely important.
