Depth is over rated. Like you said. Starters play monster minutes come playoffs. Celtics already did the depth thing with no room for solid players to get minutes. Didn’t win them a championship. They went to 7-8 man rotation anyway come playoff time.
Disagree re: depth being overrated. Yes, in the playoffs the stars play more minutes and rotations are generally reduced to 7-9 players. But during the regular season, depth is what allows star players to cut back on minutes so that they are rested for the playoffs.
