Coach K is NOT an NBA coach.
International competition is still not the same as the NBA and he had the greatest players in the NBA on the same team.
You can't make coaching in the Olympics the same as having NBA success.
He isn't going to have Kobe Bryant, Carmelo Anthony and LeBron James on the same team in the NBA although he managed ego's well. But that said, a gold medal holds a lot more "all for one" in it than an NBA Championship. Ask Pau Gasol.
And international competition is very one sided in terms of the US NBA players.
That's why team USA rarely loses when they send their best.
It doesn't translate into coaching effectively at the NBA level with a young team or even a veteran team for 82 games against NBA level competition on every night.
You can try to relate the two but they aren't relate-able. Olympic success =/= Same success as an NBA coach.
Coach K is an NCAA and college coach and one of the greatest of all time. And that's where he should stay.
I get that you like the guy, but he should stay in college.
Most of what you're saying is that Coach K has no reason to leave Duke, which I agree with.
His system will work at the pro level because of the intangibles he has developed throughout his career and throughout coaching USA Basketball. He knows how to manage superstar talent, which is more than we can say about half the league's coaches. What makes a coach like Phil so special? His ability to manage players. What makes a coach like D'Antoni such trash? His inability to do the same.
Coach K commands the respect of a Kobe Bryant, or a LeBron James. People want to play for him for a reason. There's something that all these executives and GM's see in him that makes them consistently consider him for a job. There's a reason he IS consistently atop the ACC and coaching a final 4 team. He's been doing this for 20 years.
I'm not relating Olympic success to success as an NBA coach (and I can make the argument), but the fact that he has won at an elite pace at different levels proves his qualifications for an NBA job. Success is success. When you consistently succeed at multiple levels (under different personnel), than you're good enough to implement a system and coaching style that can make you successful at an even higher level. You're telling me that Mike D'Antoni can win 60 games in this league, but Coach K can't even coach in it? Mike Brown can take us to the playoffs in this league, but Coach K can't coach in it? Not buying it.
You're questioning Coach K's ability to adapt to the NBA, which is ridiculous when you look at what he's done. He coaches basketball players. Period.
