Trevor Siemian's name appearing at the tail end of this list is likely a surprise for most. However, this should go to show just how much more was asked of Siemian in 2016 than the Broncos could have ever possibly hoped for, as they likely never envisioned a scenario where they would need him to throw 20.8 percent of his passes into tight coverage. With the collapse of both Denver's running game after C.J. Anderson's injury and the overall woes of the pass protection, Siemian needed to make more difficult throws in aggressive situations than originally anticipated. To his credit, he responded well and his 48 completion percentage on tight window throws was the sixth-best among starting quarterbacks. Even the short throws became high-degree of difficulty ones for the Broncos quarterback. His 18.4 tight window percentage on passes that traveled less than 10 air yards was the eight-highest, but again, his 58.9 completion rate on those throws ranked inside the top-five. Siemian has some flaws in his game, there's no doubt about that, but you can take many positives from his time as the starter which saw more on his plate than originally planned for. The next head coach in Denver has to at least wonder if Siemian's 2017 season will be even better if the offense is stabilized around him, and perhaps a big move for a Tony Romo-type player is not necessary.
