I'm not sure how anyone can look at this list of backs and conclude that Domanick Davis is an above average NFL starter. I think he ranks in the bottom third of this list. I'd probably take him over Shipp/Arrington, Barlow/Gore, Anderson, and Parker/Bettis. I think you can make a strong case for any of the remaining backs being better than DD. A few of them are getting old (Dillon, Martin) and a few of them had bad years in 2005 (J. Lewis, K. Jones, Jackson), but I think they're close with DD in terms of ability.

18th in rushing yards despite missing 5 games, not to mention 337 rec yards. Yeah, he's terrible, can't see why anyone would want him, much less HOU.
