maybe this guy
Kristofer O'Dowd, Southern Cal, 6-4, 304, 3, O'Dowd was the first center in the history of the program to start as a true freshman, but it was a history of injury over the next four seasons that defined his USC career. O'Dowd logged several hours in his medical evaluation at the combine and surely faced repeated queries about his durability and longevity from potential employers. They won't soon go away until he proves his twice-dislocated right knee, surgically repaired shoulder and other minor dings and dents aren't long-term issues. Shoulder problems, especially for offensive and defensive linemen, can be neon warning flags. Still, O'Dowd could go in the third or fourth round. He showed at the Senior Bowl he can anchor against NFL-caliber size -- Baylor nose tackle Phil Taylor, for example -- which was invaluable considering he had been praised mostly for his mobility. - Jeff Reynolds
