Take this for what you will, considering the source is the oft-criticized John McClain, but I found a really interesting small note in this article on Houston's "worst-case scenario.":
The Texans are expected to use a first- or second-round draft choice on another outside linebacker.
Wait a tick, you mean all those mock drafts that had them going for a wide receiver could be wrong? Who on earth would have thought the Texans would go for a defender?? Oh, anyone who pays attention to Houston and their draft tendencies, that's who.
It doesn't guarantee that Houston will take a guy like USC's Nick Perry in the first round, but if one of the top hybrid guys falls? That's a definite possibility. They could also target someone in the second round, much like they did with Connor Barwin and Brooks Reed.
Either way, I'd bet that Houston doesn't end up with a receiver in that first round.
