Durant never hinted he wouldnt sign an extension. He's said many times he enjoys OKC and it fits his personality. This isnt a surprise at all.
Is 5yrs $85mil the most OKC could offer him in an extension? I know there are rules of how much you can make given the years in the NBA. I wonder what the yearly breakdown looks like. Trying to figure out what player in the NBA signed a similar deal to get a sense of how the year to year salaries look.
