I'm late to the party and the original clip from youtube has been removed. The clip below shows the shove and punch but I'm assuming not as much of the aftermath discussed previously.

The one thing I can agree with is the lack of urgency on the part of the officials after the initial shove. Maybe this came out of nowhere but this is a reminder of the importance of dead ball awareness and trying to put out fires as quickly as possible.
On a side note, I lived in South Bend for 3 years and know the Washington coach, Skylar Diggins step-father, very well from my time there as well as professional connections since I moved back to the DC area. FWIW, he's a great guy, does a ton in the community, and his family is first class all the way. He's also done a good bit of officiating himself.
All of that has little to nothing to do with discussing the officiating aspects of the play but just thought I would add that given the title of the original link.
