Last week, Adam kicked off the preseason position rankings by looking at running back, the league's most star-studded position in 2012.

Today, we're going to take a look at the position that puts every player under the spotlight: quarterback. We're ranking the top 10 individual players at each spot and then offering team rankings a little later on. These rankings are based on past performance and potential for the 2012 season, placing a bit more emphasis on their track record to this point.

Quarterback is an intriguing group heading into '12. Here's our Top 10:

1. Denard Robinson, Michigan, senior: Say what you will about Robinson's faults -- and we've said plenty about his sometimes erratic throws and Big Ten worst 15 interceptions in 2011. Robinson remains one of the best playmakers in the country and a three-year starter who's got plenty of heroic moments under his belt. He showed improved passing mechanics this spring and should benefit from his second year under Al Borges. And we all know what he can do with his feet. With the league's top precision passers from 2011 all having moved on, Robinson inherits the top spot.

2. James Vandenberg, Iowa, senior: Only 17 returning players in the FBS threw for more yards in 2011 than Vandenberg, who had 3,022, plus 25 touchdowns. His completion percentage needs to improve, as does his road performance, and he won't have Marvin McNutt around anymore. But he's easily the most polished pocket passer in the league heading into the season.

3. Braxton Miller, Ohio State, sophomore: Miller still has a lot to learn and he'll be doing so in an entirely new offensive system. Yet he showed flashes of brilliance last year, such as his performance against Michigan or his game-winning play versus Wisconsin. He's got the athleticism to be a tremendous dual threat quarterback. Matched with Urban Meyer's creativity, Miller has enormous potential.

4. Taylor Martinez, Nebraska, junior: Martinez put in a lot of time this offseason working on his throwing motion. His dedication to self-correction is very encouraging, and a better understanding of Tim Beck's offense plus more experienced receivers could lead to a higher completion percentage than last year's 56.3. If Martinez can become a reliable passer to go along with his explosive running skills, look out.

5. MarQueis Gray, Minnesota, senior: Gray had a rocky beginning to the season as he adjusted back to the quarterback position and a new coaching staff. But in his last five games, he averaged 255 yards of total offense. Of returning Big Ten players, only Robinson, Vandenberg and Martinez were responsible for more total yardage than Gray last season. Like many on this list, Gray has worked on improving his mechanics and accuracy. There isn't a more impressive physical specimen at quarterback than this 6-foot-4, 240-pounder.

6. Danny O'Brien, Wisconsin, junior: O'Brien has yet to play a down of Big Ten football but is the presumed starter for Wisconsin. The Badgers hope the Maryland transfer is more like the player of 2010 (2,438 passing yards, 22 touchdowns, eight interceptions) than 2011 (1,648 passing yards, seven touchdowns, 10 interceptions). Wisconsin's offensive line and running game should create plenty of open passing lanes, and if O'Brien takes advantage of that he could quickly and easily climb this list.

7. Nathan Scheelhaase, Illinois, junior: After a promising freshman campaign and solid start to 2011, Scheelhaase struggled along with the entire Illini offense. He bounced back with a good bowl game performance against UCLA and now must master the new spread attack under Tim Beckman. There are always going to be questions about Scheelhaase's size and arm strength but not about his intelligence and toughness. Does he have enough skill position complements this year?

8. Kain Colter, Northwestern, junior: Is Colter simply an athlete playing quarterback? Or can he become much more than that? Those are big questions heading into the year for a guy who filled in quite nicely for Dan Persa last year. Colter has elite athleticism but only attempted 22 passes in Northwestern's final 10 games. He could be helped by perhaps the league's deepest receiving corps.

9. Caleb TerBush, Purdue: Though he's being pushed by veterans Robert Marve and Rob Henry, TerBush got the vote of confidence as the starter from Danny Hope after spring ball. Thrust into a starter's role because of injuries to start last season, he improved as the year went on. He'll need to continue working on his decision-making, because the Boilermakers won't hesitate to go to one of their other options.

10. Andrew Maxwell, QB, Michigan State: Maxwell has attempted only 51 career passes in mostly mop-up duty. But he has spent four years in the Spartans' system, being groomed under Kirk Cousins. At 6-foot-3 and 212 pounds, he's got the physical and mental makeup needed to be a standout Big Ten quarterback. He just needs more experience.
