Johnny Unitas
Some athletes change the way we play a sport and Unitas was one of them. The former Baltimore Colts’ star was the first true modern quarterback. Amazingly, he spent 18 seasons in the NFL because he came out of nowhere. The Steelers made him a late-round draft selection before releasing him.

This was a massive mistake but they had no idea that he was going to become of football’s greatest quarterbacks. He proved them wrong when he joined the Colts and won three NFL Championships. The 10-time Pro Bowler also won a Super Bowl during his outstanding tenure with the franchise (via Baltimore Magazine).
