Looking around the NFL, it is apparent that the best teams are the ones that draft well.
Successful teams do not need to rely on free agents because they often select the right players in the draft. Other squads are set back by missing picks, choosing players that do not contribute at all.
Players often fail at the next level when character issues arise, or they are simply scouted poorly and are overrated.
These men are not necessarily going to be busts, but there is a certain risk that will come with taking any of them in the first round.
