There are more than 1,700 roster spots in the NFL and a sizable portion of those remain unfilled. With only 254 selections in the 2013 draft and hundreds of draft-eligible prospects that failed to find a home in the draft's seven rounds, there's still some quality NFL talent available on the free-agent market.
Players who aren't selected in the draft are eligible to be signed just as any other free agent (at least those of the unrestricted variety). For teams that targeted a player expected to go undrafted—or those that just have to add depth—signing undrafted free agents is an inexpensive option with very little risk.
It's difficult to find impact players in the pool of undrafted free agents, but it's not impossible. Kurt Warner, Arian Foster, Antonio Gates, Warren Moon, James Harrison and Jeff Saturday are among hundreds of such players who defied the odds to become standout NFL producers, despite being passed over multiple times by all 32 NFL teams.
Will there be undrafted stars to come out of this draft class?
Time will give us the answer to that question. If history is any indication, that's not only likely but probable.
Let's take a look at the top 50 players who went undrafted in 2013. Some of these players have the potential to be impressive pros. All they need is a chance to prove it.
