Sorry, but I heard this from a reliable source on the medical staff at NRG..............He HATED the Nix pick FROM DAY 1. Pre Combine, he let his weight get to 370 lbs, then brought it down to 330lbs with a crash program. He had always shown problems with weight and conditioning/stamina and was never projected beyond a 2 down NT. Throughout his college career, he dealt with knee tendonitis due to his weight and poor conditioning, which culminated in his senior year. In that same year, he was IR'ed in Nov for a surgical repair of a severely torn meniscus (which would not be unexpected as a compensatory injury after chronic knee tendonitis) that they were not sure would be successful because of its size and where it was anatomically and because of his extreme weight. All of this led to him dropping from a projected 1st rnd pick to a 3rd rnd pick. Of course, Smith again was the smartest GM in the room when he clamored to pick Nix before anyone else could get to him. As it turns out, his meniscus repair was not successful (up to 25% with "normal BMI/weight" fail to begin with) and Nix not unexpectedly required excision of a good part of his meniscus (a definitive predictor of bone on bone degenerative arthritic changes) prior to TC of his rookie year. All of this was why O'BRIEN WANTED NO PART OF NIX FROM THE BEGINNING.
