This is where Brad Stevens refusal to play Hunter and Rozier (and even Mickey) serious minutes during the regular season comes back to haunt him.
We already lacked depth, but for some reason Brad refused to play the rookies and here we are in the middle of the playoff serious losing our best defender and best shooter.
If we played Rozier and Hunter more, we might have been able to rely on Rozier to make up for some of the defense we lost with Bradley and and we may have been able to rely on Hunter to make up for some of the shooting we lose with Bradley out.
Instead, we will like see Terry get 10+ minutes and Turner and Smart get more minutes too. Making for the three worst shooters on the team trying to make up for losing our best shooter. 
It was just a huge mistake. Very frustrating to say the least. And before anyone says anything about rookies can't be trusted, we've played Smart 30+ minutes a game even though he has had more than his fair share of downs and very limited ups. So the idea that we can't play rookies/young guys and win has been proven very false by Brad Stevens himself.
eh , mickey isn't going to take mins from Amir and Sully who are much more experienced against NBA competition . Those would be the guys he takes mins from, he can't really play with either of those 2 because our spacing would be awful . He could perhaps play some mins with KO off the bench , but that's only going to happen if Suly or Amir get in foul trouble .
Rozier has played ok, but he wasn't going to be taking mins from AB, IT or Smart . He played some later in the year when Crowder went down , but he wasn't ready for legit mins most of the season .
Let's face it , they are rookies, they aren't going to save us .
Smart, Crowder ,KO, and Jerebko need to be the guys to step up and hit some outside shots.
