Mark Jackson is an excellent motivator and teacher, and a lousy bench coach.
There are a lot of Warriors fans out there, including me, that think Jackson lost multiple games this year solely due to his "bench mob" substitutions. He always puts in 5 scrubs at the same time in the second quarter, and they always blow the lead in a flash. Then he does the same thing at the start of the 4th, and the same thing happens agina.
In addition, with Curry, Iggy, Lee and Bogut, the team is one of the most gifted top to bottom passing teams the NBA has ever seen. When the offense is allowed to run freely, it is very effective. However, when things get tight (especially at the end of games) Jackson always panics and calls over and over for isos by Klay Thompson or Lee, and they never, ever work work. It isn't 1996 anymore. Defenses can control the isos better than ever, and those guys are not Kobe or Carmelo in isolation anyway.
The owner, Joe Lacob, knows enough about basketball to know that Jackson's playcalling is holding the team back in individual games. I'm not sure, however, that he understands how much Jackson's teaching and motivation has improved the team overall. I'm not sure about that myself, to be honest. They have become a contender, but there has been a lot of talent added too. Curry and Thompson have improved under Jackson, especially on defense, but Harrison Barnes doesn't seem to be learning a thing, and the bench roleplayers rarely show much.
I wish there was some way that Jackson could be the head coach but some gnome with a clipboard could call plays and substitutions.
Iggy is awesome. Not his fault you root for a dirty team.
