Drafted first overall in 1970 by the Pittsburgh Steelers, Bradshaw was expected to be the team's franchise quarterback for years to come.
But as a rookie, he threw 24 interceptions and only six touchdown passes.
He completed just 38% of his passes.
Perhaps the most amazing thing is that Bradshaw started only eight games that season yet still managed to chuck 24 interceptions.
His QB rating of 30.4 that season remains one of the lowest in pro football history.
"I had to get tough mentally to survive and I did and I am very proud of myself for being able to handle all of that stuff," Bradshaw told CBS Pittsburgh of his early career struggles in the steel city.
Bradshaw hit his stride after a few seasons, and he eventually led his team to four Super Bowl titles.
He's now enshrined in the Pro Football Hall of Fame.
