The bench usage is interesting. My guess is that Ainge would prefer Nader and Yabusele get some minutes over what they got the first 20+ games which is zero. The President of Basketball operations knows a couple of things:
He spent a draft pick and a developmental year on each of these players.
If they play for 76 seconds miss one three and go back to the bench for four more dnp's fine. But, what are they doing here then? They have contracts and never letting them play....ever is, well, a waste of resources.
The other thing Ainge knows is that the Celtics aren't going to win a title this year, barring injuries to the leagues top 7 or 8 players. Thus, giving specifically these two players a chance to get better might be useful.
When rotations like this use to happen out of nowhere, I assumed the team was showcasing bench players whom would be involved in the swap.
Nader has 7 mpg and 2 ppg
Yabusele has 4.5 mpg and 2 ppg
Beyond hall of famers, no rookies/2nd year NBA player is going to get anything going without time. I honestly can't say if either of these guys will ever play much, but, might as well give them a couple of shots at showing something beyond turning it over and missing shots which they have proven they can do.
