15. Perennial Backup
Some quarterbacks know they will never be regular starters in the NFL. That’s okay because they still make a lot of money and avoid a lot of head trauma. But they are also the butt of many people’s jokes because they have no meaningful legacy. When they do play, fans shake their heads in frustration. “Brian St. Pierre in 2010 at home vs. the Ravens,” said a Panthers’ loyalist. “I was in attendance like always and boy was that awful performance.”

By the time St. Pierre joined the Carolina Panthers in 2010, he had only thrown five passes in his NFL career. Furthermore, he had two appearances to his name. But they made him their starter for a game against Baltimore and paid the price. He completed just 13-of-28 passes and threw two interceptions, with one touchdown. That was his final NFL appearance.
