Pretty selfless move by Kevin Durant. One point thats important to keep in mind is that he has a player option for year 2, meaning he can (and probably WILL) become a free agent again next year.

Also, next year he would qualify for a "supermax" contract like Curry got this year, so he's probably going to get a 5 year $200M deal next offseason.

It's going to be tough to keep all of the players at that point. My bet is that Klay ends up leaving, but you never know!
