Two Back Attack is the norm... Who's got the best?

I wouldn't consider a two-back combo to be "very good" or "great" unless both backs were at least average or above average.

1. NO - Deuce (way above average), Reggie (above average now, major potential)
2. Miami - Brown (above average), Ricky (above average to very above average)
3. Washington - Portis (way above average), Betts (above average)
4. Jax - Taylor (average), Jones-Drew (slightly above)
5. Dallas - Jones (average), Barber III (slightly above)

You could make the case for NE. Dillon is about average and Maroney is probably slightly above, as of now.

IMO, these teams don't qualify:

Chicago - Jones (average or slightly below), Benson (below average)
Houston - Not a single above average RB.
Denver - Ditto

Nice post. Would disagree with you regarding Jax; however, due to Fred Taylor's production (when he is healthy). I would consider him above average and Jone-s Drew slightly above average.

For what it's worth, Jim Brown was asked who stood out today (regarding today's backs) and his response was Fred Taylor. Says that he has all the skills and his only problem is staying healthy.

Also, based on their production in the post-season, I would say that the Bears duo is average to above average.

My list would look like this:

New Orleans: The perfect backfield.
Washington: Betts demonstrated that he could carry the load in Clinton's absence.
Jax: A healthy Fred Taylor is above average and Jones-Drew gave the O huge boost.
New England: Corey Dillon, Maroney (and K. Faulk). Maroney was a surprise and possibly a rising star.
Chicago: Where would Chicago be without the duo of Jones and Benson? Grossman would have had a poor season without this duo's production.
