In Part I of this series, I looked at the offensive skill positions, and in Part II the offensive line. Part III is focused on the defensive front- both linemen and linebackers. This may be the most difficult to evaluate in many respects, as the Vikings are moving to a 3-4 front that has subtle differences in trait and skillset requirements. There are also quite a few players with not much to form an evaluation on in terms of NFL regular season experience, so that will make the roster projections for the back half of the depth chart more difficult too.
