Let’s maybe stick to the real world as opposed to an imaginary scenario you created for Nets sweeping Bucks, as it didn’t happen. A year is also a very long time in the NBA, last year Lakers were favorites against Suns.
Giannis is 6-0 in the last six games against Durant and has turned the corner massively as a playoffs player last season. He got 50 in his last playoffs appearance against a team that is on a different planet to Nets. I won’t use the bubble to assess any team either, it was a freak playoffs that have nothing to do with the real level of most of those players and teams.
Even with KD and Kyrie back for the last few weeks Nets have got spanked against almost every half decent team over that period. They lost to Hawks despite KD scoring 55 and Kyrie getting 31, they were spanked by Grizzlies despite them getting 78 points combined, the only two times they really played well against a quality team was against Miami and Sixers. The fact they have been losing games to good teams despite getting big performances from their two guys is exactly the reason why I cannot treat them seriously as a playoffs contender, they have absolutely zero defense, cannot stop anybody. Their best defender is probably Bruce Brown. You cannot win in the playoffs with a team like this. Last year was their chance as Harden was still quite OK and they had enough offense to overcome the lack of defense, this year their defense is even worse and they don’t even have a third player capable of getting you 20 points consistently. Even if you get 40 from Durant and 35 from Irving every night (and you won’t because playoffs Irving is hugely hit and miss) that will likely not be enough when your third best offensive player is probably Seth Curry and you don’t even have a fourth player likely to score more than 10, and will stop absolutely nothing on the other end. It may get you through one series (hell, they may even beat Bucks by shooting lights out and being lucky on the other end) but it won’t give you a chance to win the whole thing.
And giving Bucks no chance against them is frankly ridiculous.
