Penn State was my team before the Sandusky scandal. That broke my heart. I still watch them but it's not the same. Anyway, I've watched Allar's entire career and this is how I see him. He has all of the measurables. He's going to test well. He looks the part but I don't know if he has "it". I don't know he's the guy or just another guy. If you watch his highlights you'll see some amazing throws but when you watch him game to game you'll see some really erratic play. His accuracy is all over the place short to intermediate. A lot of that can be fixed with good coaching and proper mechanics.
My biggest issue with Allar is that he shrinks in big games. You want big time QBs to rise to the occasion but for Allar it looks like the moment is too big. He presses and makes weird throws. I will say this though, I don't know if Penn State's offense is the best fit for him. That offense is frustrating to watch.
I'd draft him in the 2nd or 3rd round but the NFL is desperate for QBs and he'll be drafted too high.
