According to the
Milwaukee Journal Sentinel, the Texans haven't offered a contract and the Packers have. They say he'd have to gain at least 10 lbs. to play in Green Bay's new 3-4, but he has the frame to do it.
I think Montgomery could provide quality depth for the Texans at DE if they could get him at the right price. He's not an explosive rush end, but he has some quickness and pass rush skills, plays hard, and is solid against the run.
