Count me in the, "This makes no difference to me", column.
The NBA has and always will be dominated by a tiny handful of teams during any given era. That's just the nature of the game.
How strong a singular favorite any one team is doesn't change that. Even if Kawhi joins the Lakers and even if they suddenly were to be 'historically highest favorites' to win the title next year, that doesn't really mean much. That's the kind of stat that some team has to own after all.
The Warriors were able to add Durant through a unique convergence of events. In particular, the fact of his free agency happening at the exact time when the NBA's new TV contract caused a massive spike in the salary cap. That, more than anything, was what lead to their ability to form that 'super team'.
And even having done that, they still were not invulnerable to the competitive balance forces and the random fortunes of injury. They won two titles and then the CBA realities and the wear and tear grind (playing all those extra playoff games every year takes a toll) have caught up to them.
The Lakers may or may not be able to replicate being just as strong of a 'super team' as the Warriors were. Unlike the Warriors, they aren't benefiting from an anomalous spike in the salary cap to simply 'add to an already strong roster'. They have had to completely strip down to bare bones first to trade for Davis and then to make cap room for Kawhi (they hope). They could end up far more top-heavy, with their three superstars and pretty much nothing else around them. One injury to any of the big 3 could derail everything.
I will definitely not lose any interest if Kawhi goes there. It will just be part of the story to watch play out.
