I'm not sure I am following the logic that the West is weak and the East isn't. The top 6 in the West could all probably be at a minimum in contention for the 1 seed in the East.
If it's as simple as the Bucks have Giannis and no one else does, then okay, I'll buy that he is the most dominant guy going right now and that the Bucks have a good chance to repeat as champions. Maybe the Nets with Kyrie back full time have a good shot to win it all, too, but outside of that I can't really see anyone else in the East making a run at a title.
