If we run nickel 70 percent of the time then we really don't have a 3-4. We would have a 3-3-5. If Kiser is the real deal and can be a battle run tackling Littleton then we should look good. Since he hasn't started a real NFL game yet, he is a major question mark. The other problem is with such a young LB core we don't have the regular training camp sessions to employ a new DC's scheme with rookies learning where to line up and what holes to fill. Last year O was worried about the OL and it was miserable. This year the linebackers worry me.
