6. Toronto Raptors – 2018
Somehow the Cavaliers contrived to make the Finals in 2018 but they shouldn’t have been there. On paper, they weren’t a top team despite the presence of King James. However, they had an outstanding second round when they swept the Raptors in four games.

This was a major upset because Toronto had a fantastic regular season. They had 59 victories but couldn’t handle LeBron James. In the end, it didn’t matter because they didn’t have to wait long for their title. Meanwhile, James left for the Lakers at the end of the season.
