Milanovich even said during the season that the plan was to get more pressure from the defensive line than they did. According to the head coach, they had to blitz much more than they had wanted to as a resulte so I think that they will certainly be looking to upgrade the defensive line. I thought that Whiteside played better later in the season and should be brought back but there needs to be lots of competition along that defensive line. I would love to see the Argos draft a defensive lineman or two as well.
