The NFL draft is the exact definition of an inexact science. There is probably no better team to prove this point than the Dallas Cowboys. Each year, hundreds of draft hopefuls go the entire weekend without ever getting a call from one of 32 teams in the NFL. They never see their name or highlight reel show up on the television. For a short period of time, it appears their dream has died.
Post draft, teams still add several players as undrafted free agents, however. This exercise is where the Dallas Cowboys have become savants, if you will.
