Not just because of the opponent, but also:

Games are every other day again. No real rest. When has a team ever played two straight series‘ with just a 3-day break inbetween, every other day? Could be problematic for LeBron and AD.

+ Altitude.

If they get through in 6, they have 5 days off and the Finals are 2 days off between games (except from game 3-4).

This is it. Steal Game 1, defend HC. It‘s gonna be tougher to get 1 on the road after.
