As far as Arsenal's concerned, Kroenke isn't considered a great owner, and for a long time was considered to be an actively bad one.
From 2018 or so there was more praise for his son Josh, but since the Super League debacle he's spurned most of that good will as well. The feeling is that the club is just an asset for KSE, rather than something they really care about.
He does seem to be a very good owner in the sense that he's very hands off when it comes to how the team is run, which is important for the success of the management (let's watch the Warriors implode over the next two years under Lacob's failsons for an example of how not to do it).
The Warriors won 4 championships in 8 years. We won 1 in 35 years. It’d be nice if Wyc could show us “how not to do it” the way Lacob has.
Ha! Funnily enough Lacob was a part owner for the Celtics from 2006-2010, when he bought the Warriors.
My point really, though, is that the Warriors' success stems from three people: Steph Curry, Bob Myers, and Steve Kerr. Myers is no longer the GM; the odds are Kerr is also going to wander off after his deal ends this year; Draymond and Klay are looking old; and Joe "I'm the real architect of all this success" is going to be holding the bag along with his sons.
The best owners in sports, across all sports, are always the guys that have the budget to hire good people and let them get on with it. Lacob spent with abandon when he had to - but now he's not only not doing that, he's meddling more. This bodes poorly for Golden State's next few seasons.
