The Cavs have lost by 20+ two times in the last two seasons combined and zero times this year thus far (15 point loss being the highest).
They have been down by a lot over the last few seasons but more often than not, they make a game of it.
Pace and defense is the major factor and in an era where three point shooting can create large point differentials, it's actually pretty impressive Cavs have kept the 20 point losses nearly non existent.
In 2020-2021, a 72 game season, the Cavs had 17 losses by 20+.
JBB deserves some credit.
