Let me start by saying that I love Harden as a player. He's 23, smart, great handle, great in the pick and roll game. Good shooter, more athletic than he looks. Still has some upside. That said No way should he get 80 Million dollars. I wouldn't have an issue with 52 million or even 60 million.
With all the noise about NBA teams losing money. This is a huge problem right now. I would have a rating system. The only players making Max money would be obvious supertars, James,Wade,Bryant,Howard,Paul,Pierce,Durant,Aldridge,Dirk, Love,D Williams, Etc.
And if your a 4.5 star type talent. Joe Johnson,Harden,Josh Smith,Boozer, Grainger, David Lee, Etc.
These next tier type players could still get 55 to 65 million just not 80 million.
