Marist vs Iona Fastbreak Dunk Block/Charge??? (Video)

[Rooster]

Two things are going through my head as I watch this:
1. To and through? Kinda. Not enough for me to ship it though.
2. Does the defender stay up if there's no contact? I think so. The knee to the head knocked him down but that would be tough to see from the L. It looks like the C is squaring up to have a secondary whistle and send it, but stops when he sees block from the lead.

I'm in the "Definitely not a block" camp.
