The life of an undrafted free agent is an uphill climb.
After seeing the entire NFL draft come and go without their names being called, undrafted free agents sign for little or no guaranteed money. They live on the fringes of rosters. One misstep, blown assignment or bad practice can mean a pink slip.
In fact, many undrafted free agents already received one in rookie minicamps.
However, it is possible to rise from UDFA to NFL starter or even superstar. Cornerback Malcolm Butler made the climb from undrafted free agent out of West Alabama to two-time Super Bowl champion and hero of Super Bowl XLIX.
