I've always thought Redding was overrated. Definitely an awesome specimen, but he has no pass rush moves. He might make a better OLB than a DE.
Assuming the Texans end up with a top 3 pick, trade down to acquire multiple picks and draft the best difference-maker available, offense or defense.
Just what I'm thinking, but I'm partial to Roy. He works too hard and has too high expectations to not want him. Plus he's a freak...
