Bills host Vikings DT Jimmy Kennedy

The Buffalo Bills have been slow to act in free agency. That's not unusual for them, and new general manager Buddy Nix has stated his intention to build through the draft.

But this year the Bills have many holes to fill. They're overhauling their defense, converting to a 3-4. Suitable personnel is missing.

The Bills finally might act on their defensive conversion. Jason La Canfora of NFL Network reports the Bills will host defensive tackle Jimmy Kennedy on Thursday.

Can the 6-foot-5, 320-pound Kennedy handle the Bills' opening at nose tackle?

The Bills would have to project how he'd look at nose tackle because the four teams Kennedy has played for operate out of 4-3 defenses.

Kennedy's career has been a disappointment. The St. Louis Rams drafted him 12th overall in 2003. He has been with five teams (released by the Denver Broncos in 2007 before getting into a game) and has started only 31 games.

He is coming off a decent season with the Minnesota Vikings. They picked him up in late 2008 as an emergency replacement when the Williams Wall (defensive tackles Pat Williams and Kevin Williams) faced suspensions for violating the NFL's policy on performance-enhancing substances.

Kennedy was the primary backup in 2009 and, as NFC blogger Kevin Seifert writes, "made more plays than you would think, but probably had something to do with at least one Williams and Jared Allen usually being on the field with him."

Kennedy recorded 18 tackles, three sacks, four tackles for losses and seven hurries in the regular season. In three postseason games, he notched three tackles and one sack.
