Let's take a look at the Warriors' assistant coaches since Steve Kerr arrived prior to the 2014-15 season:
-2014-15 -- Alvin Gentry, Luke Walton, Ron Adams
-2015-16 -- Luke Walton, Jarron Collins, Ron Adams
-2016-17 -- Mike Brown, Jarron Rollins, Ron Adams
-2017-18 -- Mike Brown, Jarron Collins, Ron Adams
-2018-19 -- Mike Brown, Jarron Collins, Ron Adams
As you can see, there hasn't been a single change in three seasons.
Additionally, player development coaches Bruce Fraser, Chris DeMarco and Willie Green have been on staff for several years.
Why does this matter?
The California Sunday Magazine recently published a conversation between Kerr and legendary head coach Phil Jackson.
One exchange between the two:
Jackson: "Have you made any additions to your coaching staff, Steve?"
Kerr: "No. We haven't had much turnover at all the last couple of years, so that's a concern as well. I think we could actually use a little bit of a change in that regard, but you can't always dictate that."
