I think the issue with the whole Warriors thing, is that GSW would be considered top 2 or 3 in odds of winning it all WITHOUT KD (assuming Steph, Klay, Draymond, Andre etc are 100%). Bron went to a team that hadn't proved anything yet. It wasn't like he joined the Heat right after Wade won in '06. What he joined was sort of an unknown since Bosh was new as well. KD joined a team that had played in the last 2 NBA Finals. It would be like Jerry Rice and Barry Sanders signing on to the 90's Cowboys...overkill.
It also shows me that KD is the only transcendent superstar on their team. Without KD, Houston probably wins this series in 5 or 6 and goes on to win the title. Curry is a great player but we saw a couple of years ago that one super-Alpha (LeBron.....plus some help from Kyrie) is enough to take down one of the greatest teams ever. KD may not be super-alpha in between the ears, but I'm not sure there's a more TALENTED player in the league, 'Bron included. At the time of the signing, KD seemed like he was just extra. Now, the league has caught up a little and GSW needs KD just to stay ahead of everyone else.
