Huge blow to the Chiefs as Roaf may be the most important member of that offence. Last year in weeks 2-6 the Chiefs offence looked pretty ordinary when he wasn't around. When he was back the Chiefs had a dominant running game which in turn opened up a lot of options in the passing game. In the last 6 weeks of the season that KC offence racked up a lot of yards running left behind big Roaf.
So if you were thinking of taking Larry Johnson in your fantasy pool, maybe you were thinking Priest Holmes might make for a good backup guy....don't do it too early as I think they'll have pretty average seasons as the Chiefs O-line that used to be great has lost two great guys in Roaf and Welbourne on the tackles and only replaced Welbourne. The rushing Touch Downs may not be quite as plentiful.
