http://msn.foxsports.com/nfl/story/5834838 29. Texans The Texans have been a 3-4 team since their inception, but they've never had four good linebackers to rub together. New coordinator Richard Smith is switching to the 4-3; now, he just needs to find three lukewarm bodies. Marlon Greenwood made 112 tackles last year, but his average play occurred 6.8 yards downfield. Free agent Sam Cowart isn't toast yet, but the butter is on the counter. Kailee Wong, Shantee Orr, and rookie DeMeco Ryans will battle for the Sam position. Many of the bench players are 3-4 specialists who will get cut if they can't fit the new scheme.
