Executing a perfect draft strategy is not as easy as simply selecting the best player available on the board, especially once you start factoring in off-field issues and injuries into the mix.
Take St. Louis Rams defensive back Janoris Jenkins or Quinton Coples of the New York Jets, both of which had off-field issues entering the 2012 draft, and yes, both were taken early by their respective teams.
Jenkins has been a hit for St. Louis, while Coples has seen limited time in his rookie year.
Selecting such polarizing players can be a major gamble. Just ask the Dallas Cowboys, who have the oft-disciplined Dez Bryant on their roster. It can be boom or bust.
Every draft has this type of player, including a few already constituting the 2013 NFL draft.
