Problem with that line of thinking is that it ignore natural progression of young players. Warriors were still a crazy young team so who is to say they couldn't have just improved with Jackson as well. Not to mention that it's not like Kerr came in wanting to make Draymond an integral part of the team. The owner asked Kerr to give Draymond more minutes and then David Lee went down. The team looked so good with Draymond playing that he couldn't go back. Who's to say Mark Jackson couldn't have stumbled into the same thing. People forget that Warriors were giving the Spurs trouble until Steph hurt himself midway through that series. It's not like the team was having no success under Jackson. So to say he was horrible is just completely off base. To say Kerr is better is one thing but to say Jackson was horrible is senseless.
Listen man, you are talking to a person that thinks professional coaches are interchangeable ( and no I didnt steal that from lebartard I have been getting negged for that opinion since sohh days)
So A lot of this does lend itself to luck (Draymond Green & the players getting better) but there are some emperical things that Kerr did that was different from Jackson
This team passes the ball more, runs in transition more, runs Curry off of screens more.
The lineup last year that was responsible for the #1 Offense and #1 Defense did not play a single Minute under Jackson
Curry plays defense under Kerr he didnt play a lick of D prior to that.
