The Detroit Lions have acquired 30-year old linebacker Julian Peterson from the Seahawks for DT Cory Redding and a reported 5th round draft pick.  This was a outstanding trade for the Lions as Peterson will give them some toughness and playmaking ability at linebacker.  Peterson played in all 16 games for the Seahawks last season and he made 86 tackles, defensed 5 passes, had 5 sacks and forced 4 fumbles.  Peterson has now played in 127 games in his NFL career and he has made 643 tackles, defensed 52 passes, has 46 sacks, forced 16 fumbles and he has 8 interceptions. 

Cory Redding is a bit overrated as he has not lived up to the big contract the Lions gave him.  He played in 13 games for the Lions last season and he made 38 tackles and had 3 sacks.  This was a outstanding trade for the Lions.
