The Texans entered the second day of the draft with three picks in the second and third rounds, and they filled needs with each selection. The Texans chose South Carolina safety D.J. Swearinger (second), North Carolina offensive tackle Brennan Williams (third) and LSU defensive end Sam Montgomery (third). On the third and last day of the draft Saturday, the Texans will have five picks in the fourth through seventh rounds, including two in the sixth. On an afternoon when their No. 1 pick, Clemson receiver DeAndre Hopkins, was introduced to the media, general manager Rick Smith was making the next three picks and not moving up or down on the trade market. Not many rookies get an opportunity to be mentored by their idol, but Swearinger will play with veteran Ed Reed, who signed with the Texans as a free agent. “I’m blessed, truly blessed, right now,” Swearinger said. “I watched Ed Reed — him and (the late Washington safety) Sean Taylor. (Reed) is definitely a guy that I’m looking forward to learning from and feeding off of. “Back in high school, I started watching him. (Reed and Taylor) are some of my idols I looked up to when I was in high school.” Pick will learn from best Swearinger (5-11, 208) is a former corner who’ll play both safety positions for the Texans. “He’s very athletic in the mold of safeties that we like,” defensive coordinator Wade Phillips said. “He can play the strong safety or free safety. He can cover a slot guy if you need him to. He’s very versatile that way. He’s smart, tough, aggressive — all the things you’re looking for. “He’s a big hitter with good range. He can get in the box. He also fits in your sub-package. That’s what (Glover Quin) played for us, when the sub-package is playing over the tight end and being able to play the running game, too. We played that at least 50 percent of the time, so it’s almost like adding a starter.” Quin, who started with Danieal Manning, signed with Detroit and was replaced by Reed, who’ll be 35 next season. The Texans were looking for a young safety for Reed to groom. One reason they wanted Reed is because he takes so much pride in helping younger players. Shiloh Keo, entering his third season, improved in each of his first two seasons. He’ll benefit from playing with Reed, too. Swearinger takes pride in being a hard hitter.
