I would argue that it's harder to find a coach like Stevens than it is top talent. Now when you factor in the bad body language, constant sulking, and overall attitude of Cousins, it's simply a no brainer.
I completely and wholeheartedly disagree.
Look at the teams who have one championships in the past 10 years. How many of those teams had what would have been considered top tier coaches? I can really only name one, that being the Spurs.
How many of those teams had top tier players? Pretty much every one of them.
You can get to the finals if your head coach is merely 'pretty good', but it is nigh on impossible to make the NBA finals if your best player is merely 'pretty good'.
The Celtics won a title with a fresh big three and Doc Rivers as a coach. When they had a less fresh big three and still had Doc Rivers as a coach in their final year, they missed the playoffs.
A coach can only do so much.
Plus when you have a player as elite as Cousins, then even if it doesn't work out personality wise, there will always be other teams will to throw the world at you to get him in a trade. Superstar players have huge value as trade assets, at the very least. Dwight Howard has a terrible injury history and is a 10x bigger idiot than Cousins is, yet if Houston wanted to trade him now he would still bring a huge return.
Jordan and Kobe are almost famous for being terrible to work with and making life hell for other players, and yet they also have something like 9 championships between them.
Likewise Lebron has displayed had bad body language, constant sulking and poor general attitude since the day he got into the NBA, and he has 3 championships to show for it. Who do you think was the biggest reason for those titles - Lebron or Spolestra?
