Came across this analysis on Bulls Reddit* which is an exhaustive statistical (NBA.com) breakdown of the Bulls this season between Boylen and Hoiberg. They’ve now played nearly the same amount of games under both, having gone 24 games in the season before firing Fred and now there’s been 20 games since.
*(do not recommend, unless you want to see lots of MSPaint-edited works of Markkanen’s head on a My Little Pony with the caption “DAD”)
And oh, what games they’ve been! Boylen, even in the midst of an eight-game losing streak, still has a slightly better win% than Hoiberg, but nearly everything else is worse.
