Bronco knew Memphis had a kicker who could make that kick, but they were hurrying up to line up for the kick and probably would have called timeout themselves if not for fear of icing their own guy. The hurried kick missed horribly only to find out bronco saved him and let him compose himself, measure it and pound it through forcing 2nd OT.
If the game ends with that missed kick, there is likely no "brawl" since Koroma is not on the field to be "jumped". So that is pretty much Bronco's fault too.
For the OP...that second part is TIC and I am almost 50!
