The C's were an absolute juggernaut in the 1st quarter of Olynyk's 8 starts last year, Off. Rat. 122.2, Def. Rat. 93.7, Net Rat. +28.6. K.O. also had the best Net Rat. of any starter last year of +6.5.
1. I.T/Smart or Bradley/Crowder/K.O./Horford starting lineup. You can pull any 2 of them early in the 1st qtr. and bring them back with the bench. There is absolutely no reason to not be keeping at least 3 of I.T., Smart, Bradley, Crowder, K.O., Horford on the floor during almost all relevant game minutes.
2. Never put these 4 on the floor together again! I.T./Bradley/Smart/Crowder super small ball just doesn't work, never has never will. They can't get stops and leaves the C's undersized at every position. In 43 minutes so far this year they have a Def. Rat. of 128. Last year in 124 minutes they had a Def. Rat. of 110.8.
The big man rotation would work just fine if Horford 32 minutes, K.O. 28, Amir and Jerebko 18. The Celtics being so undersized at the guard and wing spots simply cannot afford to go small with the bigs.
