JR can't hold all the blame, all Cavs on the court should have called time out. Announcers said right before, Kerr told his guys, make or miss = time out.
No time out prep from Lue?
Missed free throws by Cavs
A few 3's with toes on the line counted as 2's
Definitely some favorable home court advantages calls.
But Cavs had their chances.
Hope the rest of the games are this close.
