First I have to ask the question...are we rating the Top 5 backs in terms of production or pure talent? Cause they are so many factors to consider...it's like comparing Ribs vs. Steak without have a clear judging criteria.
People are using yardage as argument for their Top 5 backs, but hardly anyone has Tiki Barber and Curtis Martin in their Top 5 list. Even though both backs were in the Top 5 in terms of Yardage production last year. So saying that if McGahee would have played all 16 games he would have had 1500+ yds...hence making him a Top5 back is rediculous. We have two backs who did rush for 1500+ yds, with a 4.7yds/car (Tiki) and 4.6 yds/car (Curtis Martin) while McGahee has a 4.0yds/car average. So for those making those arguments for someone out of pure biasness should apply their criteria for everyone and see where their backs line up in terms of Top 5.
My criteria is this...proven year after year consistent production and has always displayed their immense talent.
Proven, hence should be consider for Top 5:
LT, Curtis Martin, Shaun Alexander, Corey Dillon, Edgerrin James, Tiki Barber, Ahman Green, Deuce McAllister, Jamal Lewis, Priest Holmes, Ahman Green
Immense Talent, until further proven should be left out of consideration of Top 5 backs:
Ricky Williams (Took a year off, needs to reprove himself), Rudi Johnson, Clinton Portis (Production drop off without Denver's Oline), Reuben Droughns, Fred Taylor (Consistently Injured, never really proven sustain production), Domanick Davis, Kevin Jones, Willis McGahee, Julius Jones, Steven Jackson
Don't know where to put them:
Warrick Dunn, Chris Brown, Duce Staley, Brian Westbrook, Travis Henry, LaMont Jordan, Michael Bennett
