Sean Reynolds, Block U: He definitely appears to be the favorite. I still think Johnny Manziel could make some noise and Terry Bridgewater is putting together a very impressive season. His biggest problem, of course, is that Louisville plays absolutely no one this year.
Chris Landon, UW Dawg Pound: Mariota is a hot name because the other hot names have faded away. The problem is that MM has not yet faced any legit defenses. He'll get challenged pretty well by Stanford, Oregon, UCLA, Utah and even WSU. I think Mariota is fantastic, but he hasn't been as sharp passing the ball this year. I want to see him actually put a team on his shoulders just one time to win a game before we give him the title. Otherwise, Johnny Manziel looks solid and Jameis Winston continues to amaze.
Jack Follman, Pacific Takes: I would say that Mariota is the favorite at the moment and that his main competitors are the quarterbacks of the other undefeated teams that could be at the end of the season - Teddy Bridgewater, AJ McCarron, Jameis Winston, Braxton Miller, Blake Bell - and of course everyone's dear friend Johnny Football.
Jason Bartel, Arizona Desert Swarm: I don't think he's the favorite right now, I would go Jameis Winston from Florida State at this point over Mariota. Braxton Miller missing a couple of games certainly helps, and a couple other guys have had their struggles. Mariota needs to be able to do put up some big numbers and a couple highlight reel plays this weekend at Washington and then again down the road at Stanford.
Noah, Addicted to Quack: As long as Oregon keeps winning and his numbers stay where they are, I think he is the favorite. But it is an uphill battle for a west coast player who is not at USC, so I think his margin for error is smaller than the players behind him.
Josh Schlichter, Pacific Takes: Mariota's odds are the best the conference has simply because his team has the best shot to go undefeated and he's putting up a bunch of touchdowns. Stanford doesn't have a real number-hungry Heisman candidate, but Brett Hundley from UCLA may have a real shot at the trophy considering the stages he'll be on in a few weeks in Palo Alto and Eugene. Guys like Bishop Sankey will have a very tough time getting back into the chase after early season losses. All in all, it's Mariota's award to lose in the Pac-12.
Connor Pelton, Building the Dam: I like Tajh Boyd at the moment, but that's just because he's played in bigger games than Mariota has. Marcus will certainly have his chance to shine against stiffer competition in the coming weeks, and if he keeps up this kind of production, he gets my nod.
