Someone made a video on FB of all of the first day's breaks, showing only the breaks. Doung was clearly WAY slower than Shaw in all of the breaks. It wasn't even close. I can't tell if the ref called any of them illegal. The video creater had his own commentary of what was ok, and what was bad, and it was covering up if the ref took any action.
With that background info, I could def see Shaw going nuts if HE was called for a slow break on Day 2, especially if Doung wasn't called for any on Day 1.
ps, what was the final count?
