To many people who can only visualize the term "butt fumble" when Mark Sanchez is mentioned, the phrase "Super Bowl-winning quarterback Mark Sanchez" is the NFL verbal equivalent of oil and water. There is just no way those words can go together.
Denver Broncos coach Gary Kubiak has been clear that Sanchez is not guaranteed to take over as the team's starting quarterback in 2016. It would also make sense for the Broncos to go out and get another quarterback with potential.
Having noted these caveats, in the event Sanchez does end up under center for the Broncos in the 2016 campaign, he would give Denver a good chance at becoming the first back-to-back Super Bowl champion since the 2005 New England Patriots.
