The Washington Redskins have their biggest challenge up to this point in the season awaiting them on Sunday.
Denver, now led by arguably the league's best quarterback, Peyton Manning, is one of the toughest team's to beat this season.
In fact, it wasn't until Monday's 39-33 loss to Manning's old team, the Indianapolis Colts, that Denver actually lost a game.
Meanwhile, the 2-4 Skins are coming off of a 45-41 thriller in which they edged out the Chicago Bears for just their second win of the season, a game that shouldn't have been as close when you consider Chicago played most of the game with a second-string quarterback.
That fact alone lead's you to believe that Washington doesn't stand a chance against Manning's Broncos Sunday evening.
Then consider the fact that starting safety Brandon Meriweather will be inactive due to a suspension for illegal helmet-to-helmet hits in the Chicago game.
The safety position is already thinned and Washington could also be without Reed Doughty who has yet to be cleared for play due to concussion symptoms.
If he's unable to go, rookie Bacarri Rambo will likely be next in line to start along with Jose Gumbs.
Manning leads the league in passing yards (2,565), touchdowns (25), and passer rating (123.3), so it's safe to say that Washington's defense will have it's hands full.
These are the four things Washington needs to do in order to be on top when the clock hits zero.
