ST. JOSEPH, Mo. (AP) – Chiefs running back Jamaal Charles sounded off on the ineptness of his offensive line last season following Wednesday’s practice at Missouri Western State University. Rarely one to speak out, the Pro Bowler acknowledged the hodge-podge of players the Chiefs had block for him was a big reason why he was less productive last season. It was also a big reason why he was banged up almost the entire way.

Kansas City lost starting guard Jeff Allen to a season-ending injury in Week 1, then had to make do with fill-ins Mike McGlynn and Jeff Linkenbach the rest of the way. Not only is Allen back in the mix, but the Chiefs traded for Pro Bowl offensive guard Ben Grubbs in the offseason – much to the delight of Charles.
