Fantasy Upside
After earning the starting job last season, Trevor Siemian posted decent numbers in 14 games, throwing for 3,401 yards and 18 TDs to only 10 INTs. Under Gary Kubiak’s system, the offense was fairly vanilla, and the conservative game plan limited Trevor’s numbers. However, in Week 3 contest versus a Bengals team that forced Siemian to throw, he torched them to the tune of 312 yards and a career-high four TDs. He still has great WR weapons to throw to in Demaryius Thomas and Emmanuel Sanders, who can both take a short pass and turn it into a big gain.
Fantasy Downside
While Siemian has the accuracy and the mindset to remain the team’s starting QB, the Broncos traded up in last year’s draft to take Paxton Lynch, and you have to figure at some point they’d like to see what they truly have in him. While Siemian was serviceable as the team's signal-caller, he passed for less than 250 yards four times and missed two-and-a-half games due to injury. Like Lynch, who is more the deep ball threat, Siemian will be learning a new offensive system under OC Mike McCoy.
2017 Bottom Line
The former seventh-round pick heads into the regular season as the No. 1 QB on the depth chart, but will receive some doubts if he has a bad game. While Siemian emerged again as the top signal-caller to start the season, the Broncos have a challenging schedule and could fall out of the playoff race early in a tough division. If that happens, expect to see Lynch under center. With that in mind, neither QB makes for a good fantasy draft pick with the uncertainty surrounding the position.
