How likely is it that the top 4 seeds in the East are all from the Atlantic Division this year?

Sorry Brooklyn Nets, I don’t think you have a shot. But to me these 4 teams being at the top feels likely:

New York Knicks Philadelphia 76ers Boston Celtics Toronto Raptors

Now most likely another team or two takes the regular season more seriously (similar to the Cavs and Pistons) and grabs one of these spots, but how likely do you all think it is that those 4 are in some order the top 4 seeds at the end of the regular season?

If not, which teams are most likely to finish ahead of them?
