Ryan Clark knows a thing or two about what undrafted NFL players are going through after going three days and hours without seeing their names in the draft.

Clark was a standout defensive back at LSU who went undrafted before signing with the New York Giants in 2002 and beginning his NFL career. He would eventually play for the Pittsburgh Steelers and then-Washington Redskins before retiring and joining ESPN as an analyst.

During his career, Clark won a Super Bowl and was a Pro Bowl player, proving that undrafted players can have an impact on an NFL roster.

«Not being in the draft hurts. It’s hard to accept that nobody believed in you, but the sooner you do it, the better. It’s important that one person believes, and it’s you. Embrace your supporters, raise your head and get down to business work. It’s time to team up,» Clark tweeted Saturday.

Clark is just one example of an undrafted free agent who made it big in the NFL.
