There's some unexpected alliteration among the top quarterbacks in the nation: Heisman hopefuls Johnny Manziel and Marcus Mariota have been joined by Oregon State's Sean Mannion.
The 6-foot-5 junior has thrown for 2,511 total yards with 25 touchdowns and he's had just three interceptions. He's averaging an eye-popping 418.5 yards passing a game to lead all FBS quarterbacks, and he's also the leader in total offense with an average of 406.3 yards a game.
A more traditional drop-back passer, Mannion is completing 32.3 passes per game (fourth nationally), and has a quarterback rating of 166.6 (11th), while leading a team that is ranked No. 1 in passing offense.
''I think he's a grounded guy that doesn't lose sight of why this is happening,'' Beavers coach Mike Riley said. ''It's not an accident. He's well prepared, he's got experience and he's got the talent. He understands that preparation is the key.''
For comparison's sake, Manziel has 1,835 yards passing with 14 touchdowns and five interceptions for No. 7 Texas A&M, but he's also run for 438 yards and five scores, and repeatedly shown that he can take over games - with last Saturday's 41-38 come-from-behind victory over Mississippi a case in point.
Mariota has thrown for 1,724 yards and 17 touchdowns for the second-ranked Ducks, and he has yet to throw an interception. The unflappable sophomore is also capable on his feet, with eight rushing touchdowns. As with Manziel, Mariota benefits from a higher national profile than Mannion.
Other quarterbacks in the national conversation include Clemson's Tajh Boyd, UCLA's Brett Hundley, Florida State's Jameis Winston and Louisville's Teddy Bridgewater.
Mannion is starting to generate more buzz, however, including a fledgling ''HeisMannion'' hashtag on Twitter.
His accomplishments come despite an offensive line that has been in flux. He's also been lauded for carrying the Beavers while their running game has faltered. In Oregon State's 52-24 victory over Washington State on Saturday, Mannion threw for 493 yards and four touchdowns. The Beavers rallied from a third-quarter deficit with five unanswered touchdowns.
Brandin Cooks, Mannion's favorite target, caught 11 passes for 137 yards and two TDs, raising the total touchdowns between the two at 18, a new school record.
''Have we? Oh geez. I didn't even know,'' Mannion said.
In equally humble fashion, Mannion is all about his teammates.
''We feel good about our team,'' he said. ''We feel we're getting better and better each week. Honestly, from our perspective, we let our play take care of itself. If we can continue to play good football, only good things are going to happen for us.''
Oregon State was undecided at quarterback heading into the season. Riley was evaluating both Mannion and senior Cody Vaz, both of whom saw success last season when the Beavers went 9-4 after winning just three games in 2011.
Mannion started Oregon State's first four games last season but injured his left knee and required arthroscopic surgery. Vaz stepped in and won the next two games, giving the Beavers their best start since they also went 6-0 in 1907.
Mannion finished with 2,446 yards and 15 touchdowns with eight starts in 10 appearances, while Vaz, hampered late in the season by a left ankle injury, threw for 1,480 yards and 11 touchdowns in seven games and five starts.
Riley settled on Mannion a week before this season's opener against Eastern Washington.
''Sean's attributes are obviously his ability to get the ball just about wherever you want on the field,'' Riley said at the time. ''Along with his knowledge about where we're going and what he should do with the ball.''
Oregon State was ranked No. 25 in the preseason, but the opener was a disaster with the Beavers falling 49-46 to the lower-division Eagles. They've rebounded since, winning five straight and going undefeated so far in three conference games.
The Beavers travel Saturday to California (1-5, 0-3) which is adjusting under new coach Sonny Dykes. The Golden Bears are wary of Mannion because they rank last in the Pac-12 in pass defense, allowing opponents an average of 321.8 yards a game.
''He's just a good player,'' Dykes said. ''He makes good decisions, he's very, very accurate and he gets the ball out on time. They execute their offense very well.''
Dykes should probably confer with Colorado coach Mike MacIntyre. Mannion threw six touchdowns in a 44-17 victory over the Buffaloes late last month.
''He's kind of a daredevil when he throws it,'' MacIntyre said. ''He threw into double-coverage three times against us and three times Cooks came up with it. We should have had three picks, but Sean Mannion can throw the football.''
