The Nets team they played weren't stacked though. Kyrie got hurt in G4 (the Nets were up 2-1 at the time) and missed the rest of the series. James Harden missed the first 4 games and wasn't the same when he came back. They started and played Bruce Brown 52 minutes in Game 7.
Again, it's not the Bucks' fault - you can only play who is in front of you. But the truth is they barely got by a Nets team that was crushed by injuries and likely lose if either Kyrie or Harden is 100% all series.
To be fair, it should also be said they won without Giannis in some big ECF games.
Hopefully we don't have an unprecedented number of injuries next season like we did this year.
