Can someone offer a good explanation for subbing

less than six minutes in? It was 16-4. Starters were ROLLING. Everything was clicking. We are playing on four days rest. As soon as we subbed, Carolina got two layups on drives to the rim, our offense became terrible, and we pissed a way yet another double digit lead.

but hey, we won 20 games, all is well
