Baseball, like hockey, involves an incredible amount of luck in the postseason. Bad bounces of the puck, power plays at the wrong time, softly hit bloop singles vs. rocket line drives that turn into double plays...ehh, it is slanted towards the Yankees/Sox but everyone needs breaks in the playoffs. The '90 A's were a million times better than the Reds and got swept.
I agree with your thoughts on the Spurs & Lakers, but that is my point. They had/have top 5 stars and won championships. The Trailblazers and Rockets who NBA analysts love as up & coming teams don't and they have a 0.00% chance of winning it all.
