Spencer Larsen

As part of Denver HC Gary Kubiak's zone-blocking offense, the fullback will return to the roster. The Broncos haven't featured a true fullback on their 53-man roster since Chris Gronkowski in 2012, and Spencer Larsen boasted the last part-time role in the running game in 2008.

Twenty-three NFL teams used fullbacks last season. The Broncos will join the group this season with Juwan Thompson and Joe Don Duncan, signed last month, the current candidates to fill the vacancy. Kubiak also will look to add depth through the draft, which starts April 30, or with a street free agent.

The story went on to say that the Broncos tried to throttle up their running game after a humbling November loss to the St. Louis Rams. Pro Bowler C.J. Anderson blossomed, and the story also pointed out the undrafted tailback will enter offseason workouts as a starter. The author feels the balanced attack left quarterback Peyton Manning ineffective and lacking confidence. With Kubiak, power-based sets will increase in multiple formations, including the pistol, a concession to the shotgun Manning has mastered.
