11. Kurt Warner (1994)
Warner took one of the most unusual routes to the NFL. He was the quarterback behind the Greatest Show on Turf when he played for the St. Louis Rams. But Warner showed remarkable resolve to make it that far. This was because his NFL career almost ended before it even began. The Green Bay Packers released him after he went undrafted.

He wallowed through the Arena Football League before he received a second chance as back-up for St. Louis (via L.A. Times). But even before he played for them, he featured in NFL Europe for Amsterdam. Finally, he became the starter in Missouri after Trent Green’s preseason. The rest, as they say, is history.
