The Vikings will be without starting left tackle Bryant McKinnie for the first four games of the 2008 season due to him violating the NFL’s personal conduct policy.  This will hurt the Vikings big time as the teams he will be missing games with all have good DEs (Green Bay, Indianapolis, Carolina and Tennessee).  Converted guard Artie Hicks looks like the replacement the Vikings are going to go with.  With that in mind Tarvaris Jackson better have his head on a swivel because he’s going to be hearing a lot of footsteps coming from behind him.
