Watching the 60 minute replay, a couple things stand out, but the biggest ones are that Koen Entringer might have had the two plays of the game on 3rd down. The first on a perfectly timed blitz and sack on the late drive where Penn State had to kick a FG. The second on 2nd down on the last drive where the RB could have got a first down but he stopped him 4 yards short.
X also had a PERFECTLY timed blitz on the last play that disrupted the Penn State enough the QB immediately had to run for his life. If you watch the replay, if they don't get that pressure Penn State had a great play drawn up with the guy in motion would have easily had a first down.
Phil Parker coached Iowa has always been pretty shitty at timing blitzes, but in this case these two were perfect.
