Coming off a bye week, the Denver Broncos will be fresh and rested in Week 11, which will probably be necessary as they will be facing one of the league’s better teams in the Minnesota Vikings on Sunday.

The Vikings are undefeated at home this season and are riding high following a big road win over the Dallas Cowboys last week.

The Broncos will have their hands full in this game and will need many things to happen in order to pull the upset. Here are four things to watch for in this game.

1. Minnesota’s rushing attack

The Vikings rank third in the league in rushing yards behind only the San Francisco 49ers and Baltimore Ravens, a team that does much of its damage on the ground with the quarterback.

In terms of a power rushing attack, the Vikings might be the best. They run the ball right at you and right through you.

That has helped to make Dalvin Cook a legitimate NFL MVP candidate. The team also has a solid backup running back in Alexander Mattison and that duo creates plenty of problems for opposing defenses.

2. Brandon Allen

How will Allen play in his second start at quarterback? Going up against the Vikings on the road will certainly be a stiff challenge.

Allen played well in his first start against the Cleveland Browns, but even he has to know that his grip on the starting job is tenuous as fans and many within the organization are going to want to see Drew Lock get his shot sooner rather than later.
