It isn't so much the fact that the Broncos stand at 4-0 that's impressive about the record. There are currently four other teams with an undefeated record.
It's the way the 2013 Broncos have done it.
To call it domination would be an understatement. The Broncos' average margin of victory in their four victories has been 22 points. Peyton Manning has thrown 16 touchdown passes and zero interceptions for the best four-game start by any quarterback in NFL history.
"I think he has, again, started where he left off last year and improved on that," Fox said. "We added some weapons, I think personnel-wise our guys have brought in some guys that have helped us. And he’s an incredible player as far as the way he prepares and communicates things to his teammates."
When you look across the board, there aren't many weaknesses you can pinpoint on this roster.
The offense is by far the best in the league, averaging nearly 45 points per game behind Manning's unstoppable passing prowess. The defense is a unit full of playmakers despite two of their best players—Champ Bailey and Von Miller—having yet to play a single game in the 2013 season.
The special teams unit is stacked, as return man Trindon Holliday already has two return touchdowns on the season.
And so the inevitable question pops up more and more with each dominating Broncos win.
"Can the Broncos go 16-0?"
The question isn't "can they?" but "will they?"
