A take on the other topic, but basically a guy no one knew about, thought would amount to anything, perhaps someone everyone thought was overrated and turned into a true stud for years and years in the league
I think being undrafted, or a very low draft pick probably helps your cause on this one
I'm gonna throw Ben Wallace out there - I mean the guy was undrafted, tried out for the Celtics and they wanted him to be a swingman, lands in Washington, where he was solid, traded to the Pistons where he became a perennial all defensive player
