Who is Celtics current biggest rival in the east

Sixers are most hated.

Toronto most talented rival next to us.

Wizards are most dangerous with superior guard play nearly equal to us.

Sixers are my pick. The biggest reason we will continue to beat the Sixers  is their lack of PG play regardless of Simmons IMO.  They dont have a PG who can control the tempo at a high level and run the offense at peak efficiency.  They also lack a real go to scorer but Embid may become one. If Fultz ever develops or they get a high caliber PG like Wall or Lowry  then we will be in trouble. They will be a double handfull.

I voted Toronto as I think they are the best team not in Boston, though I do think Philadelphia is a bigger "rival" just given the history and the fact that they have actually played recently in the playoffs.

I think there is also an argument for the Cavs as the team that has eliminated Boston from the playoffs the last 2 seasons and 3 of 4, though with James leaving I think that "rivalry" is gone.
