The veteran, who hails from Houston, is waiting to receive a better offer than the Texans' bid. The youngsters can handle the speed and special teams; Keenan McCardell would bring experience and professionalism to a group that has a lot to learn. You can't ignore the effect quarterback Matt Schaub should have. Andre Johnson said he noticed it in offseason workouts. "When you look at it, the differences that I see is that with David you had to wait on the ball a little bit more," Johnson said a few weeks ago. "With Matt, he's pretty decisive with what he's doing. He's going to get back in his drop and let the ball go. When you're in your route, you don't have to wait on the ball or anything like that."
