No, actually that is not what happens. When the Spurs have won championships, twice the team has had a bunch of new faces that needed a while to gel, and once the team has been downright dominant until injuries hit and it had to squeak its way through to the end.
This team does not have a bunch of new faces. In its supporting cast, it has a bunch of old faces who have grayed past their primes.
I know you think you're cool being sarcastic with fans who recognize this team has fatal flaws, but just because you are capable of shoving your head far enough up your ass that you no longer can notice the problems, it does not mean suddenly the sun is shining outside.
This team is not athletic enough nor does it rebound well enough to beat the best teams in the West, and it will require personnel changes at the trade deadline to change the inevitable outcome.
