ST. JOSEPH, Mo. (AP) – Tamba Hali jogged down the long, grassy hillside to the practice field at Missouri Western State University, the modest crowd on hand for the Kansas City Chiefs’ practice bursting into applause.  Yes, the veterans have finally arrived at training camp.  One day after agreeing to a five-year, $60 million contract, Hali and the Chiefs enjoyed their first full-squad practice since arriving last week. Veteran free agents had been unable to participate until Thursday, when the new collective bargaining agreement was ratified and league year officially began.  Hali joined newcomers such as wide receiver Steve Breaston, defensive tackle Kelly Gregg and fullback Le’Ron McClain on the practice fields. The Chiefs still wore only shoulder pads and helmets as the coaching staff takes a cautious approach to getting everybody up to speed.
