Clark, Looney, McCaw and James, all have the makings of inexpensive rotation players and they'll always be ring chasing veterans willing to take the minimum. Unless James develops into it, starting center could be the one significant weakness for a while, but 29 other teams would trade for their "issues".
The previous 2 iterations of the Warriors weren't unbeatable either and both Bogut (age) and Ezeli (injury) are nearing their best before date anyway.
How does it not "seem like it'll work out" this season? Nothing is guaranteed, of course, but by every conceiveable metric, they're the clear cut best team in the league and unfortunately, barring the unforeseen, they're going to be championship favorites for the foreseeable future.
