That means less than nothing. I'm talking about actual cap space.
I don't get why you're being obtuse about this. I don't mean to sound offensive, but it doesn't make sense. The Warriors are at $35 Million in salaries next year and $4 Million in roster charges (assuming they keep the holds for Curry and KD). So they would have $69 Million in cap space. Durant's max is $35.6 Million, so that pushes them down to $33.4 Million. Curry's max is $30.5 Million. So that leaves $2.9 Million in cap space. To put that into perspective, they couldn't even give Zaza an option, because he and McCaw would have put them over. , I doubt if West was even able to get an option this time around.
To say that a team who has four players, one prospect and only two $3 Millionish contracts to offer in a landscape where mediocre guys are getting $20 Million a year has nothing to worry about in terms of depth is absurd. We're talking about the same summer where three superstars and about a dozen other high-level guys will be available. We could easily see another "superteam" or two forming, including one in San Antonio. The Warriors aren't going to have such an obvious pick of ring-chasers next season if they fail to win it all this year.
(EDIT: I will say that I forgot about Curry's cap hold for some reason. That gives them a bit more money (provided the CBA doesn't change [which it may if the owners are seriously that concerned about what the Warriors are doing]) that gives them $10-15 Million in space. That's more manageable, but it's still not that great.)
Indeed, that's the reasoning, but it has no bearing on the reality.
