NFL Draft steals: Tom Brady, other late-round picks who rose to football, financial stardom

Top college football prospects get most of the attention during the NFL Draft process, but some of the league’s most recognizable players on and off the field were late-round selections – or weren’t drafted at all.

NFL teams generally use late-round picks and undrafted rookies to provide roster depth. These players sign contracts with little to no guaranteed money or job security. In most cases, undrafted first-year players sign minimum contracts worth about $480,000 per year.

Still, some prospects have managed to parlay their unheralded starts into lengthy, lucrative careers. Others have played their way into the Pro Football Hall of Fame.

FOX Business breaks down the most successful NFL players who were late-round picks or went undrafted below.
