Yes, they missed that call. In the same play, they clearly showed prior to that helmet flying off a UK oline man holding an UGA DL's facemask for a prolonged period.
It should have been off-setting. Nonetheless, I don't think UK had the game stolen from them. I do think there were a number of questionable calls in the LSU South Carolina game that cumulatively tilted the field in the favor of LSU.
Though I am an UGA fan who lives near Athens, so there's that.
