Cowboys signed DT Amobi Okoye to a two-year contract. Okoye, the No. 10 overall pick in 2007, is still just 27 (in June). He was out of the league last season due to an unknown medical issue. Okoye reunites with DC Rod Marinelli, who he played for in 2011 and 2012 with the Bears. Okoye has 16 career sacks and will try to earn a spot on Dallas' rebuilt defensive line.
