Sounds serious.
If KD is out for the playoffs (not likely) then the lack of moves at the deadline for Boston become much much much more controversial.
If KD just tore an ACL(Ive got no reason to believe he did havent even seen the injury) then we just passed up a really really good chance to win a ring
Though I doubt the severity of the injury is that bad, this is very, very true.
That being said, I'm still glad he didn't overpay for a Butler or George, who wouldn't have guaranteed a championship by themselves anyways. However, it would make the failure to upgrade this team even slightly via an Ibaka/Noel/Tucker/Jennings/etc. type of player (all of whom could've been attained using our lesser assets while keeping our flexibility - outside of Noel, who still would've left us pretty flexible) that much more egregious.
And you never want to wish injury on a player, but oh this would be so sweet to see if it cost the Warriors a championship. That's what they get for stacking the deck for themselves so hard and becoming the villains of the NBA. And it'd be just as awesome to rub it in the faces of all those people here and all over the sports world who said once again that there was no use competing this year since Golden State already had the championship in the bag, even though the exact same stuff was said last year, too.
