HOUSTON --J.J. Watt never takes off the red and white wristband that reads "Dream Big, Work Hard." He came up with the personal mantra himself and it's a constant reminder of his long, winding journey to becoming a first-round pick in the NFL draft. The 6-foot-5, 290-pound Watt toured Reliant Stadium with his parents on Friday, after the Houston Texans took him with the 11th overall pick on Thursday. About this time three years ago, Watt was delivering pizzas and taking classes at a community college. He convinced Wisconsin coach Bret Bielema to give him a chance, and Watt became one of the top defensive ends in the Big Ten. Defensive coordinator Wade Phillips said Watt is a disruptive playmaker whom he hopes will develop into an effective complement to Mario Williams, the Texans' all-time sacks leader.
