Just a thought---the lack of heavy back side personnel is going to cause injuries----Poyer---Hyde---etc.
McD's defense puts a heavy load on non-LB's to support in run defense. There is no doubt in my mind that this exposes both the CBs and safeties to play a larger role in run support and puts them in a position where they are putting themselves in situations to get injured.
If the team is totally committed to this fact, then I'm okay with it, but it will mean that we will need a steady supply of replacements.
