They look like they've flipped the switch defensively at least. Here's their defensive rating in the playoffs, vs pre- and post-All Star break.
Boston Def Rating
Playoffs 91.9
Post All Star 110.1
Pre All Star 105.7
Yes, it was against Indiana who everyone says (and knows) sucks balls and are worse than useless so nothing good we do against them should be counted, right? Well here's Indiana's offensive rating in this series as well as pre- and post-All Star break (when they had lost Dipo).
Indiana Off Rating
Playoffs 91.9
Post All Star 109.3
Pre All Star 109.3
While I agree performances against a washed up has been team of also rans like Indiana need to be taken with a grain of salt, I don't subscribe to the theory that just because they suck our performances against them are meaningless. The offensive rating of this useless bunch of no hopers (which coincidentally is the same pre-and post-ASB) is around the same as our own post-ASB rating which was 109.7. They haven't broken 100 points in the 3 games they've played us.
Now what remains to be seen is whether we can flip the offensive switch for what remains of this series and what is coming up ahead.
We've definitely done it defensively, you could have argued that keeping Indy to below 100 a game wasn't all that hard considering how shorthanded they are, but this Milwaukee team is an offensive powerhouse and we kept them to 90 points.
Offensively I think we struggled at times during the Indy series but we played a lot more PnR against Milwaukee (mainly because they were giving us open shots) and it led to a lot of points and assists. Our ball movement was good and we shot 54% overall and 41% from 3. We probably won't do that again (Kyrie admitted as much) but there's definitely a greater sense of urgency within the team, as well as a resilience that wasn't there during the regular season.
