Both teams were basically at full strength (unless if you think Okoro and Dean Wade are significant pieces). The C's shot poorly most of the game, Jaylen was in foul trouble and Scott Foster was on one. Despite that, they were actually up double digits for a good chunk of the 2nd half and came out with a nice road win.
That's a statement win. Cleveland may still be the team to beat in the East but I don't think they look as "invincible" as a few months ago.
