Getting rid of Mark Jackson would be a mistake.
I agree, that said tho, he does need better chemistry with his staff.
Numerous sources said he didn't spoke to Mike Malone for months last year

that's absolutely crazy and unacceptable for me, now this with Scalabrine.
Mark Jackson looks like a motivation, family first, behind the players coach, but the coaching staff and general manager (the latter whose chemistry is kinda of funky too btw) is the priority, staff chemistry should always come first.
Also he is a defensive minded coach, maybe hiring a offensive coordinator would be a good idea. One that he would speak to of course! Most people look at this team see huge offensive potential, guys that can move the ball, good shooters. And all they run is lame isolations, post-ups and hero Curry ball.
This results in 13th rank in Offense. The 3rd in Defense is surprisingly in a kinda of freakishly good way. I mean Igoudala could not be that impactful could he?
To me that shows a bit of miss coaching, I could be wrong, maybe MJax is a defensive genius and he is right shaping this team like the Bulls, but it just look weird.
That defensive credit is what makes me think we should keep him. But if he keeps having trouble with the staff members, Jerry West and Bob Meyers will move on, I would bet on that.
Oh and one last important detail, both Mike Malone and Scalabrine were defensive assistants which makes the whole staff problem more alarming cause its on the end we are having success.
