Tom Nalen would play his entire career in the National Football League with the Denver Broncos, where he started all 187 Games at Center.  Early in his career, Nalen would win two Super Bowls with John Elway as his Quarterback, and during those ring acquisitions, he was in the midst of a four-year streak of Pro Bowls with two First Team All-Pros.  Nalen would get his fifth Pro Bowl and third First Team All-Pro in 2003, and he would play at Mile-High until his retirement in 2009.  Considering how many non-Terrell Davis Running Backs, he helped exceed expectations, Nalen's value can be easily quantified.  

It is one thing to be highly touted out of college and rack up serious statistics in the National Football League.  It is quite another to do that when you go undrafted.  Rod Smith lit up the league when nobody saw it coming.
