The West is just crazy loaded. I think even the 4th or 5th best in the West (Rockets/Spurs/Wolves-tier) could beat the best in the East in a series, maybe even in less than 6 games. Assuming health obviously which I know is another factor.
The East, I agree with Moranis on Detroit. I did think NY and CLE and ORL would all be a lot better and in the Top-4 in some order, but CLE/NY have been a bit inconsistent and ORL has looked worse than I thought so far.
Another surprise to me besides Toronto, is Miami. Powell has been an awesome addition for them and they are now the 3 seed at 12-6 and honestly, they've looked great. And they've also played some games without Bam and/or Herro too.
