And, to be honest, that's probably wise. By the time you get to the second round, there's really no time to workshop radically different schema than the ones that got you to the postseason in the first place. You have to trust what you did will work -- particularly when it gets you home court for the entire postseason your team survives to play in.
But as much as sudden, tectonic shifts in play style may be a desperation move with little record of success, smaller moves largely within Bud's system should be our first expected adjustment. The Bucks like playing a drop zone on defense that, while brutally effective against most opponents, doesn't do much to stop Boston.
Expect lineups that will be more effective at switching as a result -- but this is a move that will require personnel currently unavailable to Milwaukee in the form of Malcolm Brogdon (and to a lesser extent, Donte DiVincenzo) to reach the team's optimal version of a switching-capable lineup. Luckily for the Bucks, Brogdon may be able to return as soon as Game Three, but they can still make some minor changes in this direction that will help another minor issue.
The Bucks basically split their backcourt min evenly between Bledsoe (25) / Hill (24) at PG & Brown (22) / Connaughton (24) at SG. Not knowing who your main guys are can't be a good thing. And the fact that Connaughton had the 3rd-most FG attempts on the team is pretty nuts.
A team that's really trying to get past talented, high-level competition in the postseason cannot be fielding marginal starters big minutes in the postseason, and Budenholzer playing four guards north of 20 minutes a game simply can't continue. Expect a shrinkage in that rotation, with Bledsoe taking most of George Hill's minutes at the one, and Sterling Brown most of Pat Connaughton's at the two.
Bledsoe may be smaller with a shorter wingspan, but he's much better at switching than Hill, and Sterling is not only bigger than Pat, he's also shooting much better deep, which is what they need to give Giannis his best looks on offense (.500 compared to .267).
If I were Boston, I'd spend a little extra time studying up on Bledsoe and Brown in particular, especially in the limited context available of them actually attempting switching defenses in anticipation of these likely adjustments from Milwaukee -- good planning matched with good execution might just land a knockout blow to their opponent on Tuesday night.
