(SportsNetwork.com) - Gentlemen, start your survivor pools.
When the unbeaten Denver Broncos host the winless Jacksonville Jaguars this weekend in Colorado, it'll be more than just a matchup of a pair of early season 0s.
While the Broncos have approached historic league levels of elite play through a 5-0 start, the Jaguars have been forced to read commentary in which they've been compared to all-time lowly squads, including their own 4-12 expansion version from 1995.
The contrast prompted odds-makers to install Denver as a 28-point favorite, a number that ties the recognized mark for highest spread -- initially reached when the Baltimore Colts were a four-touchdown pick to defeat Atlanta in 1966.
The Falcons covered, and no game since the merger in 1970 has featured so high a number.
But there are plenty of numbers in 2013 to warrant the gap.
Denver is first in the league in scoring offense, averaging 46 points per game and coming off a 51-point effort last week at Dallas. Jacksonville is second- to-last in scoring defense, has allowed 32.6 points per game and has kept only one foe -- Oakland in Week 2 -- below 28 points.
Meanwhile, the Jaguars have scored only 51 points in five weeks, including three games in single digits.
The Broncos' average of 489.8 total yards per week is also first in the league, while Jacksonville's per-week clip of 379.8 yards allowed per game is 22nd-best among 32 teams.
Oh, and Denver has won 16 consecutive regular-season games, while the Jaguars have dropped 10 straight, 19 of their last 21 over two seasons and haven't won two in a row since weeks 13 and 14 of 2010.
After winning their first four games by margins of 22, 18, 16 and 32 points, the Broncos were forced to compete for four quarters last week in Dallas and finally won, 51-48, when Matt Prater hit on a 28-yard field goal as time expired.
"We don't go into each game trying to see how close we can make it," coach John Fox said. "If you fall asleep at the wheel, you wreck. Sometimes dealing with prosperity is more difficult than the adversity. Our guys understand that. They understand it's more about the process than the results. They understand it's more about the preparation work which will relate to the performance."
Quarterback Peyton Manning was 33-of-42 against the Cowboys and finished with 414 yards and four TDs. He leads the league with 20 scoring passes and threw just his first interception of the season.
The Broncos did look vulnerable on defense, where Dallas QB Tony Romo was able to exploit them for more than 500 yards and five touchdowns through the air. Denver is last in the league against the pass with opponents averaging 347 yards per game and 29th in total yardage defense at 416.6 per week.
Defensive back Champ Bailey hasn't played after injuring his left foot in the preseason, but he's been upgraded to questionable this week and could return. Meanwhile, linebacker Von Miller will sit out the sixth and final game of a suspension connected to the league's substance-abuse policy.
"No team is invincible," Denver safety Rahim Moore said. "It's the NFL. It's hard to win in this league."
Jacksonville will once again start Chad Henne at quarterback in place of anointed No. 1 Blaine Gabbert, who's been riddled by injuries for the last two seasons. Gabbert completed 9-of-19 passes, including a 67-yard scoring strike to Justin Blackmon, before leaving a loss to St. Louis last week with a hamstring problem.
