Four-year starter who owns 18 passing records at Oregon State. Tall quarterback who sees over the offensive line. Throws with high release point. Plays with desired footwork. Can sit down and shift weight properly to drive the intermediate throws. Played in pro-style offense and is comfortable with 3-, 5- and 7-step drops from under center. When protected, shows confidence to stand and deliver with accuracy to all areas of the field. Trusted by head coach Mike Riley to make pre-snap reads and audible. Played in multiple-read offense and shows patience in allowing routes to develop. Good feel for pro-style play-action passing attack and can throw with above-average accuracy and ball placement.


Tempo of his play is a concern. Slow in takeaway from center, setup and getting through progressions. Carries ball low in the pocket, allowing defenders to swipe at it. Finished career with 30 fumbles and 54 interceptions. Poise and mobility in pocket are below average. Not considered a play-extender outside of pocket. Drops eyes and misses throwing windows when he senses pressure around him. Decision making greatly influenced by level of pressure around him. Fails to throw with adequate zip when feet aren't under him and he doesn't step strongly into throw.

"His stats and tape weren't as good this year as last year, but he flashes NFL potential in every game you watch. I thought he did the same thing at the Senior Bowl practices." -- NFC area scout

Bottom Line

Tall, rhythm thrower who shows an ability to play with confidence and accuracy when used as a game manager within an offense featuring a strong rushing attack. Mannion needs plays to stay on schedule or his confidence becomes shaky and the turnovers start rolling in. Mannion lacks arm talent to carry an offense, but has enough ability to become a capable backup.
