Brief bio of this Shonka guy:
Dan Shonka, has been involved in player personnel work for over 4 decades. He is one of, if not the only, NFL Draft Analyst to have played the game, coached the game, recruited high school players on the major college level, and scouted professionally. Shonka scouted for National Football Scouting, the Philadelphia Eagles, Washington Redskins, the Kansas City Chiefs, and the Philadelphia Stars of the USFL for a combined 16 years. Scouting is not a hobby. He has built his home and raised his family on his experience as a player personnel evaluator and he remains a team consultant.
