The issue with all of this Ogaju is that this years Bucks team would have WAXED the Cavs, Celtics, 76ers, and Raptors of last year.
The current Raptors with Kawhi/Break out Pascal would do the same and the 76ers with Butler/Harris are also a better team than last year.
Going to game 7 of the conference finals is an achievement relative to who you are playing along the way. The Celtics of last year and the Rockets of last year did not face comparable obstacles.
Edit: Also the C's team's last year offense was trash even worse than this years, especially once Kyrie went down. They won on D. Now Kyrie hurts you on the defensive end, but he improves your offense by more. The issue became because of this teams awful chemistry and fit they stopped playing defense when their shots didn't go in. (also they stopped executing the offense if they missed more than two in a row)
