Imo, definitely not the Hawks. I'm very low on Trae Young. The Mavs are a good shout because of Luka. The same goes for the Nuggets because of Jokic. Can't think of an eastern conference team. Embiid's injury history scares me. Giannis ain't a half court player. The majority of playoff games are won in the half court. Not to mention, he relies a lot on athleticism. Will he be equally dominant in his early 30s? I guess he will, barring injuries. The Heat might be a good shout. They already got Bam, plus they are a popular free agent destination. Anyway, it's practically impossible to predict these things. Let's say the C's, cause why not?

I mean, Tatum can be the best player in a championship team in my book.
Fwiw, here's a graph I stumbled upon on reddit.

One way to read it is that Trae Young is a terrible decision maker in the clutch. Would have never imagined that the Cavs have won 75% of their close games. Obviously, it's a small sample size for all 30 teams.
