Bucs signed LB Jonathan Casillas to a one-year, $3 million contract. The deal is worth "up to" $3 million, so it's probably incentive laden. Bucs GM Mark Dominik loves stealing from division rivals, and 26-year-old Casillas has flashed every-down tools in spurts the past four seasons. In 2012, he was the Saints' nickel 'backer and recorded 31 tackles in 14 games with one start.
