The Vikings have signed safety Madieu Williams to a 6-year, $34 million dollar contract.  Williams is an enforcer against the run which means he should fit right in.  He played in 13 games last season for the Bengals and he made 74 tackles, defensed 7 passes, had 2 sacks, 1 forced fumble and he intercepted 2 passes.  Williams has now played in 49 games in his NFL career and he has made 290 tackles, defensed 34 passes, has 4 sacks, forced 3 fumbles and intercepted 9 passes they he returned 126 yards (14.0 avg) including one that he returned for a TD.  Williams was a solid addition to the back of the Vikings Defense.
