The ability to find productive NFL players goes beyond the NFL draft. Teams have identified players throughout the offseason that have skills and abilities that could allow them to make contributions even though specific weaknesses in their game kept them from being selected during the weekend.
The list of top undrafted free agents from the modern era includes former Dallas Cowboys quarterback Tony Romo, ex-Denver wideout Rod Smith, former Pittsburgh Steelers outside linebacker James Harrison, ex-Minnesota Vikings defensive lineman John Randle, former St. Louis Rams, New York Giants and Arizona Cardinals quarterback Kurt Warner and current Indianapolis Colts and ex-New England Patriots placekicker Adam Vinatieri.
