Dallas may have interest in the "Tank"

The Bills and Saints may be interested in adding Tank Johnson before training camp, according to ESPN's John Clayton. ESPN's Matt Mosley says sources close to the Cowboys indicate Dallas may also have interest.

Johnson has knowledge of Bills coordinator Perry Fewell's defense, as Fewell was once the secondary coach in Chicago. A team confident in its playoff chances is more likely to take a flier on Johnson because he's almost certainly going to miss at least the first eight games of the season.
