Here's an updated list of upcoming free agents
WalterFootball.com: 2011 NFL Free Agents
They have Soliai (Dolphins NT) listed as the second best tackle behind Ngata, and likely the best true 3-4 NT available in free agency. I really think we should look at this guy. With a lot of needs in other areas, and the emergence of Bryant later in the season, we could be set at NT. The Dolphins don't want to tag him because it would be too much money for them. I feel one of the reasons our 3-4 experiment failed, was the lack of a true NT.
