KP was injured last year for most of the playoffs and the C?s still won. This year JB is dinged up instead. Had a better bench last year, though. Could really cost us this post season.
As others have pointed out, pretty sure that is debatable. Horford, Pritchard, and Hauser all played regular minutes last season but Horford was generally a starter with Porzingis out and Kornet playing extra minutes (part of top 8). If Horford can go back to the bench, our primary (top 8) rotation will actually be better since it will be Horford and not Kornet as the first big off the bench.
Now if Brown is out or limited, Horford may be back to starting, and we will be pretty much right were we were last season with our top 8 rotation. We will have Porzingis and no or less Brown, but works out about the same.
After those top 8, last season the next 3 in terms of minutes were Tillman, Brissett, and Mykhailiuk. Of those 3, only Tillman played any meaningful minutes, and he didn't play very many. This season we will have Kornet, Craig, and I guess Scheierman as the next 3 (assuming that Brown plays). If no Brown and Kornet ends up in the top 8, probably Queta would get the #11 spot.
So if we don't have Brown, our 6-7-8 will be Kornet, Pritchard, Hauser (exactly the same as last season). Beyond that, maybe Craig sees some meaningful minutes, but even that is doubtful. And Craig is no worse than last year's Tillman or Brissett.
