So much for getting a nose tackle through free agency. According to Pro Football Talk, Adam Schefter of the NFL Network says Isaac Sopoaga has resigned with the 49ers for 5 years. Are there any true nose tackles about to hit the free agent market? I can't think of anyone. Sopoaga could have filled the huge void a nose tackle. It looks more and more likely that Miami will have to find a nose tackle in the 2nd or 3rd rounds in the draft.
