Plenty of undrafted players have been inducted into the Pro Football Hall of Fame. The list includes Dick "Night Train" Lane, Warren Moon, John Randle, Willie Brown and Joe Perry.
For many years, the draft had as many as 17 rounds, which made it less likely that a decent NFL prospect would go undrafted. But scouting wasn't nearly as thorough and sophisicated, which explained why talented players could still be overlooked.
The NFL reduced the draft to 12 rounds in 1977. It went to eight rounds in 1993 and then seven in 1994. Here's a chronological look at notable undrafted players whose NFL career began in 1994 or later.
