Siemian is neck and neck with Mark Sanchez for the starting QB job, the Denver Post reports.

Siemian's candidacy for the starting job has been talked up more and more in recent weeks, with head coach Gary Kubiak fanning the flames by complimenting the young passer in the press. Denver's lone returning starter benefits from a superior understanding of the team's offense, but it would be a shock if last year's seventh-round pick, who has yet to throw a professional pass, secures the job by the end of training camp. Sanchez is reportedly close to learning the entire offense, and rookie first-round pick Paxton Lynch is likely the most physically gifted of the three and may only lack additional experience in order to compete.
