What's amazing to me is that you're one of the few people here besides me who seems to get this obvious concept. It's just hard to believe that so many people think great players would somehow not be great players if they were on the Kings. As if a wizard is coaching the Thunder and created Durant and Westbrook via some magic spell.
And yet we saw exactly that. Durant and Westbrook and the Thunder were AWFUL under Carlesimo. I have made the point before, conveniently ignored, that they started his final season 4-29. 4-29!!! They were averaging 91.8ppg on .418 shooting. Sound familiar? Westbrook was averaging 12.2pts on .345 shooting. Durant was at 22.8 on .461 and still being accused of actually hurting his team with his presence. Scott Brooks takes over, voila, they finish the season in respectable young team fashion. Start surpising some big teams. And are on the way. Then there is Minnesota. Maybe the worst team in the league last year with most of the same personnel (Rubio and Williams, who plays limited minutes off the bench, excepted). Rubio is a nice young player, but they compete well no matter whether he is starting or coming off the bench, having a good game or a bad. In fact his numbers in wins: 11.9pts 8.6ast on .330 shooting are not much different and maybe even inferior to his numbers in losses: 10.5pts 8.9ast on .410 shooting. The superstar acquistion there was Adelman.
On a young team the coach is MUCH more important than he is on an old team. The old 80s Celtics used to infamously get by with KC Jones as a coach, but he was more player coach than actual coach coach. He made substitutions and argued for fouls, but the team was a championship experienced juggernaught and just pretty much ran itself while he played figurehead. But young teams, especially ones as young as ours, are just like college teams. And in college the coach is everything. Reason is simple -- young guys don't know how to play yet and need somebody to tell them and given them structure. By the time you reach Kobe's age/experience you know as much basketball as the coach. When you're 21/22 you don't. That simple.
And its showing for us on the court too. Cousins is getting consistent and far more efficient. Reke is running an actual offense as a PG and putting up strong PG numbers (its 15.0pts 5.7reb 6.9ast 1.3stl in the last two weeks), we've figured out a role for Jimmer, got Thompson back working as a roleplayer etc. Team assist are up. Shooting percentage is up. Coaches matter.
