I see the secondary shaping up pretty much like you suggest. I do believe they'll pick up a player or two in free agency (CB + S) and took Brandon Harris anyway as a good, young developemental talent - no way he's starts after last year's failed experiment. More picks coming today.....I think they (Texan braintrust) have to operate as though whenever free agency comes along, there might be a mad scramble where it's possible that they could end up out in the cold... There will be more picks coming today and I think you will see a serviceable defense that could possibly operate quite well without the benefit of free agency....
There's also (insert doomsday music) "gel time". Hate to say it but it's gonna take a whole lotta repitition/practice/live action before all the old parts and new parts work together as a team in this new 3-4..... It won't be fast enough for some people but hey, thems the breaks. If the Oilers taught me one thing, it is how to be patient..... 9, 10, 12 years? Pffft, no problem. Especially over things I have no control over...
One last thing... I'm really tired and annoyed of reading of the Watt pick as a "safe" pick. What exactly does that mean? What makes it "safe"? Safe as in "not going to bust"? Or safe as in "you-messed-up-my-mock-draft-you-spineless-weasels"?

Why not call it a "good" pick? A "solid" pick? Much better terms, IMO....
