So who do the Bucks still have?
Brogdon (2nd game after missing 5) / Gary Payton II
Jason Terry / Rashad Vaughn
Michael Beasley
Mirza Teletovic / Spencer Hawes
Thon Maker / Greg Monroe
I should probably note that Maker typically starts, plays a few minutes, and then is benched, to give him experience against the centers but not necessarily making him the Bucks starter in the typical sense (although it can depend game to game). He's also technically a power forward, who has a pretty good 3 pt shot that he uses decently often.
Reason why I bring this up is because I see the potential for a trap game for the Celtics. Jason Terry is far too old to be starting against the Celtics, and with Brogdon at 6'5'' I could see him and Payton II playing as most of Milwaukee's back-court. Brogdon has played Boston well both times this season (last game he had a 16/4/9)
If you go by splits, the only two teams Monroe, with his post-up ability and size, does better against are New York and Philadelphia (he and one of Okafor/the smaller Holmes off the bench is a bad mix). He averages 15/10.5/2/1.5/2 against them, in 31 minutes. Boston legitimately has issues with the type of center that, fortunately for them, is going out of style.
This is also a pretty consistent thing. Last year, he averaged 19/10.5/3.8/1.3/0.8 in 31 minutes against them (equal best for ppg with a few other teams). Year before that was 24/8.5/0.5/1.5/1.5 in 31 minutes (more ppg than any other team)
Michael Beasley had 17/8/1 the one time he played Boston, in 22 mpg, this season. He shot 70% that game. On the other hand, last year, with the Rockets, again just one game, he had 18/8 (5 ORB)/0/0/1 in 15 minutes, so there might be something to him being an issue for this Boston team. He's also averaged about 15.4 ppg in the 5 games he's started this season for Milwaukee, with 24 mpg.
These were the 5 games he started, for reference.
(@ Indiana)
(vs Detroit)
@ Brooklyn
vs Utah
@ Cleveland
So it might be possible for Milwaukee to upset and for Cleveland to get 1st seed still
