3rd round (83rd overall): Louis Nix, DT, Notre Dame, 6-2, 331.  Weaknesses – He was overweight to start the season last fall, then got hurt, which could hinder his chances of contributing for the Texans straight away. He struggled with double teams in college, which doesn't bode well for his handling same at the pro level. He sometimes lets his emotions get the best of him, which will attract undue attention from NFL officials. Photo: Jonathan Daniel, Getty Images
