Between them, they have won seven NFL MVP awards, including five in the last seven years, yet Peyton Manning and Aaron Rodgers have played against each other only once.

It was in 2008, when Rodgers was in his first year as the Green Bay Packers starter and Manning was still with the Indianapolis Colts.

Much has changed since that meeting. Rodgers has won a Super Bowl and two MVP awards. Manning suffered a serious neck injury, was released by the Colts and signed with the Denver Broncos, where he won his fifth MVP award in 2013.

Rodgers and Manning finally face off again on Sunday night in Denver in a meeting of 6-0 teams. Here's a tale-of-the-tape look at each quarterback from ESPN Packers reporter Rob Demovsky and ESPN Broncos reporter Jeff Legwold:

Tale of the tape

Height/weight

Manning: Manning is 6-foot-5, 230 pounds, and more than one defensive coach, including current St. Louis Rams coach Jeff Fisher, mentioned how "people forget how big Peyton is," and how tough. "He's there every week," Fisher said. Manning has never missed a start in a season he opened behind center. His only missed games came in 2011, after his fourth neck surgery, and that year he missed all of training camp, the preseason and the regular season.

Rodgers: At 6-foot-2, 225 pounds, Rodgers is deceptively athletic. Packers coach Mike McCarthy has said many times that Rodgers is a much better athlete than he gave him credit for when he evaluated Rodgers out of college in the 2005 NFL draft. Seahawks coach Pete Carroll said earlier this season, "He's the most difficult guy to play against us, and he's unpredictable because he is so athletic. It's just a nightmare trying to figure him out."

Age

Manning: 39. To that, Manning said, "I've had plenty of guys walk up to me and say, 'I was this age or that age when I first saw you play.' I understand it. I'm not sure I always like it, but I understand that."

Rodgers: 31. He's under contract through the 2019 season, but don't be surprised if Rodgers plays beyond that. He'll be only 36 when that deal expires. He said this offseason that "last year was the first year it felt a little more difficult to get back into the exact shape I wanted to,” but added that he streamlined his workouts, eating and sleeping habits to help in that process.

Seasons

Manning: 18. He is one of three players from the 1998 draft who remain in the league; Charles Woodson and Matt Hasselbeck are the others. Woodson had the first two interceptions of his career against Manning this season. Asked his reaction to that, Manning said, "I guess it took him 18 years."

Rodgers: 11. However, this is only his eighth as a starter after sitting behind Brett Favre for three years. How different would things have been if Rodgers had to play right away? Rodgers has said many times over the years that it was beneficial to go to a team that allowed him to develop without playing.

Overall record

Manning: 185-77 in the regular season; 11-13 in the playoffs. There's some public conversation about the Broncos potentially benching Manning if his play doesn't improve, but folks should pause that thought because Manning's team is 6-0, and he is now 44-10 in his 54 regular-season starts with the Broncos. "You know what that is," Broncos cornerback Chris Harris Jr. said. "That's ridiculous."

Rodgers: 76-33 in the regular season; 6-5 in the playoffs. The Packers went 6-10 in Rodgers' first year as a starter but haven't had a losing season since. He has led them to the playoffs in each of the last six seasons and to the NFC North title in each of the last four.

Super Bowl appearances/wins

Manning: 3 appearances, 1 win. In Super Bowl XLI on Feb. 4, 2007, Manning completed 25 of 38 passes for 247 yards with a touchdown and an interception, and the Colts rushed for 191 yards in a 29-17 victory over the Chicago Bears. In Super Bowl XLIV on Feb. 7, 2010, Manning was 31-of-45 for 333 yards with a touchdown and an interception, but the interception was returned 74 yards for a touchdown by Tracy Porter with just 3 minutes, 12 seconds left to play in a 31-17 loss to the New Orleans Saints. In Super Bowl XLVIII on Feb. 2, 2014, the Broncos entered the game as the highest-scoring offense in league history, posting 606 points in the regular season, but Manny Ramirez sailed the first snap of the game past Manning's head, and things didn't improve from there in a 43-8 loss to the Seattle Seahawks. Manning finished 34-of-49 for 280 yards with a touchdown and two interceptions.

Rodgers: 1 appearance, 1 win. In Super Bowl XLV on Feb. 6, 2011, Rodgers was the MVP after throwing for 304 yards and three touchdowns in a 31-25 win over the Pittsburgh Steelers. He joined Joe Montana, Steve Young and Jake Delhomme as the only quarterbacks to throw for 300 yards and three touchdowns without an interception in the Super Bowl to that point.

MVPs

Manning: 5. He's the league's only five-time winner of the award. He won in 2003, 2004, 2008, 2009 and 2013.

Rodgers: 2. He's the reigning MVP and also won in 2011.

Significant records

Manning: It might be easier to list the ones he doesn't have. He is either No. 1 all-time or tied for No. 1 in MVP awards (five), TD passes (537), comeback wins (43), fewest sacks (3.12 percent of attempts), Pro Bowls (14), postseason appearances (14), game-winning drives in fourth quarter or overtime (51) and career 4,000-yard passing seasons (14). He is poised to break the all-time mark for career passing yards this season, he needs 624 yards to pass Favre as Manning went into the bye week at 71,215 yards, behind Favre's 71,838 yards.

Rodgers: He ranks first in NFL history in passer rating with a mark of 106.5 and became the fastest quarterback to 30,000 yards in terms of fewest passing attempts earlier this season. He ranks first in NFL history in touchdown-to-interception ratio (4.08-to-1, 241 TDs and 59 INTs) and ranks second in NFL history for the most touchdown passes (203) in his first 100 games behind only Dan Marino (217).

Commercials

Manning: Buick, DirecTV (where the "Football on your phone" video came from), Gatorade, Nationwide ("Chicken Parm you taste so good"'), Nike and Papa John's. His MasterCard commercial earlier in his career, in which he chants, "Cut that meat!" and "You're my favorite accountant, Tommy, please, you're on my fantasy team," is still one of the most recognizable examples of an athlete pitching a product.

Rodgers: The State Farm "Discount Double Check” not only is a slogan, it has also become the name of his championship-belt TD celebration. He recently left Nike for Adidas.

Rally cry

Manning: From the 2014 season, "(Tom) Brady said he was going to play until he sucked. … Yeah, right, until you suck -- I think that's a pretty good rule right there."

Rodgers: "R-E-L-A-X," his message to Packers' fans, and perhaps his team, on his ESPN Milwaukee radio show after the Packers started 1-2 last season.

Best line-of-scrimmage call

Manning: He uses "Omaha" a little less than he used to, but it's still a familiar refrain. He will sometimes drop the names of Hall of Fame quarterbacks in his cadence, including his boss, John Elway.

Rodgers: "New York Bozo” emerged last year. This year, he has been heard saying "Orange Bozo.” No one but Rodgers and his teammates know if they're dummy calls or actual signals.
