It's difficult to overstate just how important quarterback contracts are to success in the NFL. Finding a valuable quarterback on a rookie deal has been the league's Holy Grail since the NFL instituted a draft slotting system in the collective bargaining agreement in 2011. Maximizing the time teams get to spend with those passers helps, but even once they get paid market value, franchises build their rosters and their futures around the contract of the guy they have under center.
Typically, we see about five to six quarterbacks sign multi-year extensions during a calendar year. This year is likely going to be an exception.
