It's not like they actually listen to Blatt, the problem is they have the pieces to make his offense work but Bron has to play the iso-ball bullshyt. Meanwhile Blatts sets will work if you run them with the talent they have -
They use almost no misdirections in the Cavs set, it's all LeBron + Kyrie high pick and roll, that shyt will not work against the Spurs or Warriors and LeBron seems too stubbon to realize it. If they bring in another coach it'll just be more 1-4 sets where people stand around waiting on LeBron.
