Rank these running backs

[VarlosZ]

It's a very tough question because RBs are so dependent on the rest of the offense for their success (even moreso than other positions).

I'd put Barber and Westbrook at the top because I think they were most personally responsible for their success. Of the two I always thought Barber was a lot more impressive, but I'm way biased, so take that with a grain of salt.

(On a related note: are there any Giants fans who think that Westbrook was better? Any Eagles fans who think that Barber was better?)

I ranked Alexander last, but my confidence in any of the rankings from 3rd through 7th is extremely low.
