Many players have had unique paths to the NFL in the past. Every year we hear stories about athletes who only started playing football the last handful of years. Or players that previously excelled in another sport (most of the time basketball) only to try their hand on the gridiron later on. Or players that were working menial real-world jobs before improbably making a roster. Or players that bounced around in the CFL and other developmental leagues before getting a tryout at the highest level.
But playing football at three different colleges, mostly at quarterback with a little special teams and linebacker sprinkled in, only to end up getting your shot at.
