How many is too many D-lineman for the Bears?

Rod Marinelli has never met a defensive lineman he didn't like.  That's a scary thought with the Bears heading into their third preseason game minus two such players projected to be on the roster.  DT Anthony Adams will miss the rest of the preseason with a strained calf muscle while DE Corey Wootton is still recovering from surgery to repair the meniscus in his right knee after going down on the opening kickoff of the first preseason game.  If those guys aren't back for the season opener against Atlanta on Sept. 11, then Marinelli probably will have to get through that game with no more than seven healthy defensive lineman.  The Bears' defensive coordinator may have once loaded the roster with promising young defensive ends when he was a head coach in Detroit, but it's unlikely he'll be able to carry big numbers at the position this year.  Sadly, defensive lineman don't usually make great special teams players and that is exactly what reserve defenders have to do on the Bears.  You can't keep 10 defensive linemen and still play great special teams.
