The NFL is starting a transition to more athletic quarterbacks who possess speed and agility that is absent in many passers who currently start. Kyler Murray, Josh Allen, and Lamar Jackson have all been added in the last year as first round picks, and the belief is that this could be a trend that will continue. For teams looking for athleticism at quarterback, Nick Fitzgerald could be a spectacular undrafted free agent signing for the Tampa Bay Buccaneers.
Unless you are the New Orleans Saints or just flat out unlucky, the third string quarterback on an NFL roster is not usually a well-known player.
