CBS has been doing these wonky lineups since he got to Boston. He's coaching for the season not tonight, I understand it. Either the bench will improve or it will cost them come playoff time.
This argument has never made sense to me. In the playoffs we're only going to go like 9 deep with Kyrie, Brown, Morris, Tatum, Horford, Smart, Baynes, Rozier, and maybe Semi more defense. Why should we suffer all year long with full bench lineups out there when you won't see that at all in the playoffs? I just don't think that argument makes any sense.
