Its not expecting perfection.
Its usually the more talented team wins. Clippers have more talent and are just missing Kawhi. Lakers had more talent and were missing AD/75% LeBron.
Giannis will/would be the best player on the floor in the finals. And unlike other teams they'd have their 2nd best player on the floor. (Obviously the Clippers best is with Kawhi though)
It has nothing to do with the Suns and mostly to do with the other teams. There is nothing wrong with that as no one will care (in Arizona at least) as long as they win the championship. Crazy stuff happens almost every year.
Things are destined for a Suns team to win the championship. On them to capitalize.
Sorry, but this post just skims the surface of the big name injuries which is a pretty superficial focus.
Chris Paul has played at a historically elite level for a point guard in key spots in these playoffs to help push the Suns into the Finals. He has what, 2 games with over 40 points and zero turnovers? That is historic. Kawhi doesn't stop that, just like the presences of "MVP" Jokovic didn't. The Lakers are past their prime and AD failed to put in the conditioning work to stay healthy. We have our own stars in Book and CP3 that can perform at the same level or better than the big names you mention, and a rising star in Ayton that has outperformed his counterparts in key moments in this run. Our role players are unmatched.
The chemistry this team has been able to put together involving multiple contributions from many different players, exactly the way the game is supposed to be played, has been amazing. This started in "the bubble" and carried through this season. We have had stretches with key players out, or playing injured, and managed to push through as a "team".
Your talent comparisons are debatable. But as we know, championships are made of grit, good decision making and good coaching, not just "talent". There are lots of football analogies here, guys who have not been the most "talented" but who have outperformed their opponents.
This has "nothing to do with the Suns"?? Come on man.
