Where the game was really lost

I haven’t been reading much since the heart breaking loss but my thoughts are it wasn’t the end of game interception….it was Allar’s misfire to Singleton in the first quarter that would have made it 14-0 versus 10-0 and we would have been taking a knee that last series …that was a pitch and catch he makes 99 times out of 100 and that 1 time I believe cost PSU the game…what say you ..??
