If AD doesn't care about being the highest paid player ever and wants to win, fine, let him go the Durant route.
The only thing is make sure and trade him for a butt load of assets. By the time Durant left that team had been to the Finals and was a contender.
If we lose AD we are losing 2 playoff appearances in what 8 years? Yes he is an amazing player and maybe he goes on to win a ton of rings but he's basically Garnett for us so far. Great but underachieving.
I promise you this though, we aren't losing because of not having a wing. We are losing because we don't have a PG to run the offense. If I'm Dell I sell the farm for Kemba, not Barnes. Jrue needs to spend 90% of his time off ball.
