IMO odds are Sammy goes #1. If they pass on clowney because of his rocky start, I can't possibly see using #1 overall on mack. He's solid but sure as heck not dominant like a Ray Lewis or an LT. Would you use #1 overall at that position on anything less than HoF potential?
Taking Sammy works for them because then they can cut ties with the unhappy Andre Johnson, maybe trade for a draff pick, save cap space, and position to get their QB next year. OR if hindsight were really 20-20, take carr with 33rd overall in round 2. Sammy and Carr would have been an amazing draft for them, and huge uprgade of the offense.
