Actually you're wrong. The call was ridiculous.
First off, people are confused as to even who the penalty was on. It wasn't on Prosise(#20). It was called on Will Fuller(#7). The issue with it being called on Fuller is that all Fuller did was run a slant route and Ronald Darby blew the coverage and never even tried to fight through the route. Secondly, the officials missed an absolute mugging(defensive holding) of Prosise AND then to top it all off, immediately after the final play an FSU player takes off his helmet in celebration which should have been a 15 yard penalty and automatic first down for Notre Dame and the officials admitted to Kelly and ND that "they missed it".
Notre Dame got absolutely hosed. It's not only "die hard" fans that believe it. Numerous impartial columnists and football players have said as much.
