Roach spent the past six seasons with the Bears. He has started a total of 59 games since entering the league as an undrafted free agent out of Northwestern. He has been the full time starter three of the past four seasons in Chicago, including all but one game the past two seasons.
Roach played strong side linebacker for the Bears last season collecting 65 combined tackles, 4 passes defended, and 1.5 sacks. He is being considered as a possible replacement for the departed Philip Wheeler. He will turn 28 in June.
Sims' career starts came earlier in his career. He has never been the fulltime starter for the Bengals since being chosen as a third round pick out of Auburn. He started 22 games over his first three seasons but has started just one game over the last two. The 6-4, 312 pound defensive tackle has 5.0 career sacks. He had 36 combined tackles as a rookie and has seen his numbers steadily decline every season since.
The Raiders are the right team for him to try and get his career on track. They are in need of help at defensive tackle something fierce.
