As mentioned in a previous post, understanding everything you can do before the snap on defense goes a long way in having defensive success. This video covers even more pre-snap adjustments one has at their disposal in NCAA Football 06. Perhaps the best thing about this video is how I go over how I like to shift and move my players around to get them in ideal spots to defend.
You may not have the best players on your current rosters, but you can at least help them out by pointing them in the right direction to avoid less mistakes. This video should help with that.
