1. Von Miller
Who else?
The reigning MVP of Super Bowl 50 spent the offseason on a seemingly worldwide tour that had critics wondering if he would be able to continue playing at such a high level.
Dancing with the Stars appears to agree with Von Miller.
He has returned in 2016 as though he never left, showing the same quickness and explosion that keep offensive coordinators up late at night, and quarterbacks seeing him in their nightmares.
In just four games, Von has logged 15 tackles, 5.5 sacks and his strip sack of Colts quarterback Andrew Luck in Week 2 that was returned for a touchdown was vintage Von.
Opponents try to account for Von Miller on every single play, and they are still unable to stop him.
With the first quarter of the season complete, the Broncos are still one of the top contenders in the NFL.
And Von Miller is the No. 1 reason.
