After the Texans drafted Whitney Mercilus in the first round Wade Phillips mentioned he might field five linebackers at some point this season. When I read the quote by Phillips after the draft, I wondered how this formation might work and it was discussed a couple of times in the following months on this board. Wade Phillips did just that on Sunday night against the Bears. Micheal Wilbon mentioned it in his column on ESPN. http://espn.go.com/chicago/nfl/story/_/id/8622498/chicago-bears-just-ready-nfl-elite I'm going to assume he meant to write that the Texans' defense was so unconcerned with the Bears' passing game... I've not heard of a defense that uses five linebackers except the 3-4 Eagle, but that formation substitutes a linebacker for the nose tackle, not a defensive back. I believe I saw five linebackers on the field on the fourth down and one in the first quarter when Quin forced Bush to fumble, but it's hard to pick out all the player numbers because of the camera angles. Perhaps we may see an all-22 breakdown later this week.
