3. Using the preseason for evaluation

Zimmer said that his approach to preseason games hasn't changed since first starting with the Vikings in 2014.

Ultimately, he uses the four preseason contests as further evaluation of his players.

"We're trying to evaluate our players, trying to see if they're using the techniques that we're coaching, see if they're playing the game the right way – [avoiding] pre-snap penalties, a lot of sloppy things that go on," Zimmer said.

When asked if Zimmer knows how much the first team will play in Denver he answered, "I have a plan, yes."

The Broncos have talented players on both sides of the ball, and Zimmer said that the opponent's skill level is always taken into account when evaluating.
