ST. JOSEPH, Mo. (AP) — After finishing next-to-last in scoring last season, the Kansas City Chiefs have several reasons to hope for a big offensive rebound. Pro Bowl running back Jamaal Charles is back from ACL surgery, as is tight end Tony Moeaki. A new offensive coordinator, Brian Daboll, has installed a new offense, and quarterback Matt Cassel looks to be 100 percent healed from a hand injury that shelved him for the last seven games in 2011. Kansas City also will be counting on a trio of free agent acquisitions: right tackle Eric Winston, running back Peyton Hillis and tight end Kevin Boss. Romeo Crennel, who has replaced Todd Haley as head coach, refuses to put a label on his new system other than calling it “a winning offense.”
