Tape Breakdown

Aidan O’Connell’s name gets buried in a strong QB class at the top. But the fact he’s even likely to hear his name on draft day is pretty impressive. A one-year high school starter with very little interest coming out who walked onto Purdue, became a starter, and turned into a successful college QB.

At his core, O’Connell throws a pretty ball and shows good touch and arc on his throws. He’s able to take what defenses give him, take a profit, and effectively and consistency throw underneath against zone. Versus Michigan, he started 14/15 by carving them up underneath, though he finished the game 32/47 (18 of 32 the rest of the way) once he had to push the ball downfield.

He does show anticipation on his throws and able to lead them or get the ball out before they break. Some examples.

I like his composure and makeup. Against Syracuse, he threw a terrible INT returned for a TD, a careless play to try and avoid a sack, that put Purdue in a two-score hole in the fourth quarter. He rallied the offense and took the lead on this play, O’Connell hitching and climbing and hitting his TE for this go-ahead score, though the Boilermakers blew the lead and lost.

While O’Connell doesn’t have a bad arm, he isn’t as effective driving the ball downfield against man coverage. He’ll begin to force throws and is far more effective picking defenses apart underneath. Often, he won’t even test defenses vertically until or unless he has to. And CBs can jump him in the flat while knocking away his slants. He also struggles in the face of interior pressure and that’s where he begins to force throws without the arm talent to get away with it.

And here’s that mistake against the Orange. Terrible decision under pressure that leads to a pick-six.

There’s also a consistent arc on his throws, even on screens. Know this is a far hash play but his pass has too much arc and takes too much time to get to his receiver.

O’Connell also lacks much mobility and is a pocket passer who can’t avoid free rushers or defenders who come free. Not a dealbreaker but don’t expect him to do a lot with his legs other than some minor ability to run and extend a play behind the line of scrimmage.


Overall, O’Connell is an accurate thrower who is quite effective beating zone from 5-15 yards. Against man, he looks far worse and will have issues consistently driving the ball with success down the seam or outside the numbers. There are traits to like but he profiles as a competent backup than a high-end starter. He’s beaten the odds before to make it in college and shouldn’t be counted out. But he shouldn’t be counted on either. My NFL comparison is Brian Hoyer, another Big Ten QB who had a better junior season before struggling more his senior year with a long career as an NFL backup.
