While trying to seal up one former one-year veteran in Roy Williams, the Bengals are also making an effort to keep Tank Johnson around for another season. Pro Football Talk writes that they're being told (weird sentence structure) that "the Bengals are working to keep Johnson, who became an unrestricted free agent at midnight."
Johnson started 13 of the 14 games he played with the Bengals in 2009. A foot injury slowed him early in the season. As he got healthy, he become noticeably more productive, recording seven tackles against the Kansas City Chiefs and five against the Minnesota Vikings including a quarterback sack on Brett Favre.
While Johnson teamed up with Domata Peko to become a reasonable decent duo at defensive tackle, the biggest issue this year will be depth. After those two, you have Pat Sims (who is respectable but hardly feared), Orien Harris and Clinton McDonald. I don't know about you, but crap. The Bengals could clearly look to upgrading the position after Peko and Tank, which we're sure they could look into after the first round of free agency slows down.
