I think it sucks and it's bad for the league.
Like him or not, Klay is one of those guys you can't help but admire. Probably the best two-way guard in the league and one of the best scorers you'll ever see.
Ditto for Durant. Same thing went Hayward went down.
First you feel bad for the person. Secondly, you realize as a basketball fan (regardless of who you root for) that it's a big loss for the league.
Also, maybe I'm in the minority but I've never once disliked the Warriors. I sure would've liked to see the Celts knock them off their throne, but it's such a well run franchise and you can't help but like guys like Steph and Klay.
Only guy on the Warriors I've never really cared for is Draymond. Management does deserve a TON of criticism however for how they handled Durant's injury.
