Agree there was not one thing wrong with the play calls.
1st down they were hoping psu would be ready for the run and fail to cover someone. They did a pretty good job, picket likely has a shot to run it in if he decides to run right away but it would have been close after the initial hesitation the window was closed and he wisely threw it away.
2nd a run very similar to the one they scored on but wasn't blocked at all
3rd they had it wide open but someone missed their block if picket has one second more it's a easy td.
4th of course was a missed fg
