Facing what soon could be an excess of running backs, the Chiefs traded Michael Bennett to the Tampa Bay Buccaneers on Monday night. What the Chiefs received in return was immediately unclear. The Chiefs declined to confirm the deal, but Bennett said he was informed of the trade by officials of both teams. ?It was a shock to me,? Bennett said. ?It really caught me off-guard. I heard the speculation for the past few days, but nobody from the Chiefs said anything to me, so I guessed it wasn?t going to happen. I was wrong. It?s a business. It?s just one of those things that happen.? Although he was the starting halfback during Larry Johnson?s training-camp holdout, Bennett quickly became expendable once Johnson signed his contract extension.
