It happens every year. A team has high hopes for their season, and then disaster strikes.
The starting quarterback gets injured.
For most teams this means a lost season. The backups just aren't good enough to make up for the loss. The ultimate examples being the 2011 Colts, who went from a playoff contender to 2-14 after Peyton Manning went down, and the 2015 Cowboys, who went 4-12 after Tony Romo got hurt.
A solid backup quarterback is the most important insurance plan any NFL team can have, but it's still not the easiest thing to find. These aren't exactly star NFL quarterbacks, but they're the safety net that every NFL team needs to survive a season-ending injury.
7. Colt McCoy
McCoy was not a good starting quarterback with the Cleveland Browns, but no one ever really is. However, he's been able to carve out a decent niche as a backup. The former Texas star won't blow you away, but he's a savvy veteran who would be able to keep your team afloat if necessary.
6. Nick Foles
Oh how quickly we forget. Foles was once hailed as a star in Philadelphia after coming in for an injured Michael Vick and going on to throw for 27 touchdowns and 2 interceptions in 2013. He's dropped off since then, but he's still a high quality backup to have.
5. Derek Anderson
Derek Anderson, better known as the quarterback that led the Browns to a winning record, has been a good backup behind Cam Newton for years now. He's clearly not Newton, and often turnover prone, but he offers stability behind a quarterback that often puts himself in harm's way.
4. Chase Daniel
Daniel has been a backup quarterback for seven years now and his teams have been lucky enough to only see him on the field twice. He's performed admirably both times and if his college career is any indication, he has plenty of talent if called upon again. You don't sign a bad backup to a $21 million deal.
3. Matt Moore
Moore may be a backup, but it seems like he's called upon to play nearly every year at some point. He's not the most impressive quarterback, but he has a winning career record of 15-13 and 41 touchdowns in 28 career starts. He gets the job done.
2. AJ McCarron
McCarron is one of those younger backups whose name always gets thrown around when another team is looking for a quarterback. He didn't play in 2016, but was solid when thrust into the starting role at the end of 2015, throwing for 854 yards and 6 touchdowns in three starts.
