PSU has not played anything close to a 4 quarter game offensively all year (except Washington, Purdue and Maryland which don't count). They have flashed, they've been brilliant running and passing at times but they haven't done it for a whole game.
So the argument against PSU is that they haven't done it all year, they are what they are offensively, good but not great. The argument for PSU is that if they could really put together a relatively mistake-free game on offense, starting with Allar, they could shock ND.
Wouldn't it be storybook if the PSU wideouts had a great game? I think Omari Evans is ready, I think Wallace is ready, Wouldn't it be great if, instead of flashing brilliance for half a dozen plays a game, Allar played brilliantly for 10-15 plays? Wouldn't it be great if Coach K's bizarro stuff actually fooled Notre Dame and hit some home runs against a very well coached defense? Odds are against it, but still, one can hope....
