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.  

Jack Ferrante had a unique path to the National Football League as not only was he not drafted, he never played ball in College Football at all.  In fact, he never even finished high school. 

Let that sink in for a minute.   If you were like us,  you might have automatically thought about the Mark Wahlberg film about Vince Papale, which is an excellent story in itself, but Papale was not nearly as good as Jack Ferrante.

Drafted 5^th overall out of the University of Tennessee, Jamal Lewis was an immediate offensive force for the Baltimore Ravens rushing for 1,364 Yards in his rookie season.  More importantly, the Ravens went to the Super Bowl, and Lewis rushed for over 100 Yards and a TD in their Super Bowl XXXV win.  A knee injury took him out of his sophomore season, but he came back in 2002 with another 1,300 Yard Season though it was his 2003 year that places him on this list.  He rushed for 2,066 Yards, which as of this writing, is the third-best in history.  That year, Lewis was named the AP Offensive Player of the Year.

A 5^th Round pick from Oregon State, Vic Sears would play his entire National Football League career with the Philadelphia Eagles.
