Jerome Mathis

Mathis needs to prove himself all over again after his sophomore season was pretty much lost to an offseason foot injury suffered while riding a motorcycle. Once he returned, he suffered a hamstring problem that lasted through to May's organized team activities. His commitment to conditioning has come under question, and he'll need to change some minds during training camp. In third-round draft pick Jacoby Jones, the Texans have someone who can do everything Mathis does, including return kicks. Mathis suffered a stress reaction in his lower leg and was placed on injured reserve in Oct. 2007.
