This is tough because I wouldn’t consider any of these teams to be sneaky contenders since I already expected them to be contenders: Hawks, Magic, Pacers, Cavs, Spurs, Bullets. Also the West has literally 2 playoff caliber teams.
Sneaky Contenders
Pistons: KAT is good enough to put them in the contender discussion despite a lack of depth and Durant being a shell of his former self. Harrelson is still very good, and Rose hasn’t died off yet.
Bullets: They aren’t as good as the top of the East, but winning this many games still puts them in the discussion, and I could see ebbs making a move to add more talent.
Pretenders
Bucks: The roster outside of Ayton/Kyrie is weak. Vesely is mid, and losing Oden hurt a lot.
Bulls: Turner is not good anymore, Joseph is a turnstyle on D, and Randolph is on the decline. Kawhi is incredible, but he can’t do it by himself
