05/05/2015 - Mannion ended up being the fourth quarterback selected in the draft after Jameis Winston, Marcus Mariota and Garrett Grayson. He was one of several quarterbacks the Rams worked out in the week before the draft, and Snead said that private session was "what solidified him for us." Fisher cited Mannion's "understanding of terminology, of defenses, decision-making. We sent some information, let him study the night before. We talked about it the next day and he had it down. He's exceptionally smart. Again, I think the thing that I was most impressed with was his ability to make every throw; the different touches, the deep balls, the shorter throws and then the footwork. I thought his footwork in the pocket and getting out of the pocket was much better than I saw on tape. He had a great Pro Day and he had a great workout for us."
Draft analysts said Mannion's weakness was his slow feet and delivery. Mannion knew it and worked on those things with quarterbacks coach Jordan Palmer, the brother of Arizona Cardinals quarterback Carson Palmer. Mannion said, "I know one thing that I really tried to focus on after the end of my season was really sharpening up my footwork and really cleaning that stuff up and I felt like I was able to kind of show that at the Senior Bowl and at the combine and at my Pro Day. A lot of it was really positive feedback about how they'd seen I made improvements in those areas." Asked if improving his footwork helped speeding up his release, Mannion said, "I definitely think so. I think footwork is something that can help a lot of areas of your game. Obviously, quickening my release is something that I had been wanting to do. I think focusing on my footwork and always throwing from the same base in the pocket can really speed up my delivery and get the ball out very fast." - The Sports Xchange

06/27/2014 - Oregon State's top NFL Draft-eligible prospects to watch in 2014: 1. QB Sean Mannion, RS Senior...Reportedly given a third round grade from the NFL Advisory Committee after a record-breaking junior season, Mannion elected to return to Corvalis for a final year of college football before joining former Riley pupils Derek Anderson, Matt Moore and Sean Canfield in the NFL. Mannion is similar in many ways to Anderson and Canfield. He sports an NFL-caliber frame, has the arm to make every throw and is a classic drop-back passer with limited mobility. When he feels secure in the pocket and has the time to step into his throws correctly, Mannion's touch on intermediate and vertical passes is as impressive as any quarterback in the country. He lofts the ball with perfect trajectory over the shoulder of his receivers and allows them to go get it, demonstrating pinpoint accuracy to lead his target away from defenders.
Mannion has an easy, natural throwing motion and he's well-versed in Riley's pro-style offense, which asks him to take snaps from under center as well as from the gun. While he can drive the ball when needed, it cruises, rather than explodes out of his hand. The result is that Mannion's passes look effort-less but there is some question as to whether he has the top-notch velocity to significantly boost his stock this season. - Rob Rang, NFLDraftScout.com
06/27/2014 - Oregon State's top NFL Draft-eligible prospects to watch in 2014: 1. QB Sean Mannion, RS Senior...Where Mannion can improve is poise under pressure. Mannion is intelligent and typically is able to read defenses prior to the snap. When he's fooled and his primary read is taken away, he has a tendency to drop back further into the pocket, rather than stepping up. Mannion is willing to absorb a hit to complete the pass, but too often does so while falling back (rather than stepping into his passes), erasing some of the zip and accuracy from his throws. Mannion's production (and Riley's track record) speak for themselves. He threw for a Pac-12 record 4,662 passing yards last season, including a school record 37 touchdowns. He's entering his fourth season as the starter and is a three-time team captain. - Rob Rang, NFLDraftScout.com
