Barring an injury to Slaton and/or Green (yeah - I know), why would anybody think that Walker is going to be a bigger part of the offense because of this?
He was waived at the end of the preseason, added to the practice squad because nobody else in the NFL wanted him either, and only added back to the active roster when Green got hurt in game 1. Since then, we've IR'd Taylor, but we've also added Cecil Sapp (who, as opposed to Walker, contributes on special teams). Walker's been on the roster for four out of five games, and he has yet to get a carry - even though in each one of those four games either Taylor or Green was inactive due to injury. I don't think he's even stepped on the field yet. And to top it all off, the fact that Kubes has cut him twice indicates that he might not have the highest opinion of Mr. Walker.
