The Cowboys have signed 26-year old DE Igor Olshansky to a 4-year, $18 million dollar contract.  The 6′6″, 309 pound Olshansky played in all 16 games for the Chargers last season and he made 29 tackles and had 2 sacks.  He has now played in 75 games in his NFL career and he has made 179 tackles, defensed 6 passes, has 11 sacks, forced 3 fumbles and he has one interception.  Olshansky was signed to replace the departed Chris Canty who signed with the enemy Giants and he should do a good job for the Cowboys.
