The Broncos know all about Buccaneers rookie running back Doug Martin, because the team took a long look at him before this past April's draft. If the Broncos can keep Manning from getting hit there will be some big plays available. 1. The Buccaneers signed Northern Colorado graduate Vincent Jackson to a $55.56 million contract in the offseason to give their offense some serious pop. Martin has had three 100-yard rushing games over his last five, including a 251-yard effort against the Raiders. 2. Keep Freeman unsettled.
