Carolina was very successful with Williams/Stewart/Tolbert for several years until they got old and injury prone. Bengals are doing well right now with Bernard and Hill. Patriots get a ton of production out of Ridley/Vereen and whoever else they plug in there. Colts are getting a lot out of Bradshaw/Richardson/Herron. Browns did well with Tate/West/Crowell until their o-line got messed up. Etc.

And you might notice that pretty much every big time college program plays 3 and 4 guys. In fact I would say the number of NFL teams which does not regularly use at least a two-back rotation is very small. and many are using 3 these days.

We take it to the extreme with 4, but really if you think about it the Cadet/Sproles/Bush spot in the rotation really isn't a running back, it's more a receiver position.

Don't get me wrong, I love watching Ingram run. I just don't want him getting 30 carries every game. Haslett ran Deuce into the ground with that crap and probably took 4-5 years off his career. If SP had done the same thing with, say, PT, he'd probably be washed up by now too.
