To be fair two things caused this:
(1) Lue mismanaged his timeouts which isn't new
(2) If Collison sinks that three, Indiana is fouling up three with no timeout. Therefore, they were planning the QB-WR play where Love throws it to LeBron and he quickly turns around before they inevitably foul (I'm making an assumption here but this has been the trend this season)
Problem here the above scenario didn't anticipate a miss (I know, pretty bad) which forces Indiana to play honest as we're in the bonus, so now a playoff game is being decided by JR which is lol worthy to begin with. At the moment I had a similar reaction because it seemed like Clarkson should've been open to receive a pass with 2.2 seconds on the clock (shave a second for the pass to get there and he would've had 1.2 seconds to launch a three for the win) but he's not the guy you want making decision and that shot is exactly what I expect from JR LMAO.
