I really think it depends on where you are personnel wise. If you have a young QB or young skill group, it can be huge as a stepping stone between practicing and 11 v 11. However, as a football fundamentalist, I don't care for it much. Coaches run things in 7 on 7 they will never run in the season in terms of formations, concepts and coverages. That drives me crazy and I don't find value in that.
