1. Tajh Boyd, Senior QB, Clemson:

Last Week (W, 56-7, Wake Forest): 17-for-24, 311 yards, 3 TD (69 rush yds, TD)

Season: 73-for-114 (64.0%), 994 yards, 9 TD (159 rush yards, 4 TD)

Boyd remains at the top of the list and will stay there until the Tigers either lose or someone proves they deserve this spot more. His campaign has slowed recently due to not being in any high-profile game. But his season-opening victory over Georgia looks better and better each week as the Bulldogs continue to win. Boyd’s competition will continue to hold him back until he plays Florida State at home on Oct 19, which will likely have national title implications as well.

2. Marcus Mariota, Sophomore QB, Oregon:

Last Week (W, 55-16, Cal): 11-for-25, 114 yards, 2 TD (33 rush yards, TD)

Season: 60-for-107 (56.1%), 1,003 yards, 9 TD (295 rush yards, 5 TD)

Another week, another 40-point win for the Ducks. Oregon has yet to score fewer than 55 points in a game this season and has not allowed 20 points in a game yet. The Ducks haven’t been challenged and won’t really be tested until a midseason stretch against Washington, UCLA and Stanford, all of whom are in the Top 15. Mariota will put up big numbers, but completing 44 percent of his passes against Stanford will not help his Heisman chances. The meat of Oregon’s schedule is coming, and Mariota will need to be ready for it.

3. Teddy Bridgewater, Senior QB, Louisville:

Last Week: BYE

Season: 79-for-110 (71.8%), 1214 yards, 14 TD, INT

Bridgewater is starting to lose ground to the other contenders as Louisville is starting to lose ground in the national title hunt. Their drubbing of Florida International looks good on paper, but no one really expects much from Florida Internatinal. The Cardinals’ medicore schedule continues to hurt them and this week doesn’t get much harder as Louisville heads to Temple to square off against the winless Owls. The Cardinals can’t just pummel cupcakes all season and expect to get respect from voters of any kind.

4. Johnny Manziel, Sophomore QB, Texas A&M:

Last Week (W, 45-33, Arkansas) : 23-for-30, 261 yards, 2 TD (59 rush yards)

Season: 100-for-140 (71.4%), 1489 yards, 14 TD, 4 INT (314 rush yds, 3 TD)

Manziel is back on the list despite all of his shenanigans because the kid seems to know how to play some football despite not knowing how to stay out of the spotlight. He is being incredibly efficient with the ball this season, completing at least 66 percent of his passes in each of the first five games. Though he only has four interceptions so far this season, the two against Alabama were costly. Road games against Ole Miss and LSU will be tough, but wins will go a long way toward leading Manziel to another Heisman Trophy.

5. AJ McCarron, Senior QB, Alabama:

Last Week (W, 25-0, Ole Miss): 25-for-32, 180 yards, INT

Season: 75-for-110, 882 yards, 6 TD, 3 INT

Alabama put on a defensive clinic in a shutout of Ole Miss. McCarron, meanwhile, did not do as well. He did not have a touchdown for the first time this season and the Crimson Tide did not find the end zone until the second half. Alabama will hold onto the No. 1 ranking this week, and only have a few marquee games left this season. He is already having to fight the perception that he relies on his defense more than it relies on him. McCarron will need to be on top of his game if he wants to take home the Heisman.
