With the 89th pick in the 2015 NFL Draft, the St. Louis Rams select Oregon State quarterback Sean Mannion.

CBSSports.com's Pete Prisco really likes the pick: Mannnion -- A This is nice value here at this point. I think he's the third-best quarterback in this draft and gives them a young passer behind Nick Foles.

If there was a dark horse candidate in this year's quarterback draft class, it was Mannion. The Pac-12's all-time leading passer wound up hearing his name called before Bryce Petty and Brett Hundley. Mannion draws physical comparisons to Tampa Bay's Mike Glennon, and he'll serve as Nick Foles' backup in St. Louis, which brings the Napoleon Dynamite comparisons full circle.

Then there's this comparison:

Not surprisingly, opinions differed on just what type of NFL player Mannion will be:

More on Mannion from NFLDraftScout.com's Rob Rang and Dane Brugler:

"Mannion has an attractive resume as a four-year starter with impressive production in a pro-style offense. He has adequate arm strength and accuracy, but isn't above average in either category as the ball doesn't shoot off his hand. Mannion is too methodical with his movements and tends to deteriorate when the pocket crumbles, struggling with his pocket awareness, internal clock and improvising skills, which is a recipe for disaster in the NFL. He is a high character human being with exceptional make-up and intangibles - teams will never have to worry about him off the field or not putting in enough work."

In addition to Foles, Mannion joins a depth chart that includes Austin Davis and Case Keenum. Foles and Davis will enter the final year of their deals in 2015.
