Just last year they beat Houston without kd

You're deliberately misrepresenting what happened. They had Durant for the entire series except for game, which is obviously not a meaningful sample size.

Jerebko/mckninnie/cook were all getting serious minutes. These guys are now out of the league or can’t get any minutes

Almost all of this is misleading or false. First of all, with the exception of Cook these are pretty much end-of-the-bench guys. Jerebko absorbed some minutes in the regular season but was benched in the playoffs, Mckinnie hasn't played any less with the Cavs than he did with the Warriors, and Quinn Cook has been displaced from the Lakers' rotation by the emergence of a better backup PG in Caruso. You may not be wrong, but the arguments you're making are disingenuous.
