POSTED 7:56 p.m. EST, March 11, 2007 ZGONINA CLOSE TO DEAL WITH TEXANS A league source tells us that veteran defensive tackle Jeff Zgonina is close to striking a deal with the Houston Texans. Zgonina, who has spent the last four seasons with the Dolphins, has played with a total of six franchises. He appeared in 14 games in 2006, with two starts. In our view, the no-nonsense veteran could help to light a fire under the No. 1 overall pick in last year's draft, defensive end Mario Williams.
