The Dallas Cowboys have signed free agent NT Tank Johnson to a 2-year contract.  The Cowboys needed some help in the D-Line after losing starting NT Jason Ferguson for the season due to injury.  Johnson won’t be elgible to return to the NFL for six more weeks while he serves an NFL suspension for off field conduct.  He needs to behave and get in shape because the Cowboys need his help so they can make a deep run in the playoffs this season.  Johnson played in 14 games last season for the Bears and he made 26 tackles, had 3.5 sacks, defensed 1 pass and forced a fumble.  Johnson has now played in 46 games in his 3-year NFL career and he has made 63 tackles, 9 sacks, has defensed 4 passes and forced 1 fumble.  This was a god gamble by the Cowboys as they need help with their run defense.
