Doc - I'm not sure if you meant to do this or not, but your second post is very different from your first. The first one defies all logic unless we are sitting at 2-0 with comfortable victories in both games. Since we weren't, I see very little justification for not utilizing every tool in our bag to try to get to 2-0. I'm not even sure how that conversation would go..."No, let's not use that play/formation just yet. I'm saving it for the Big 10 season." ???
Having said that, I agree to some extent with your second post. I've done some coaching at the high school level, both offensively and defensively...I prefer offense
. I don't know that coaches put in new plays to "keep players interested"...if anything they might add a play to attack a specific hole they saw on film. A lot of times though, we wouldn't necessarily add new plays as we would run our existing plays against the fronts we would see on film, and from there devise different ways with our existing playbook to attack those fronts. We might tag a run play to adjust a blocking scheme or to change some backfield action, but during the week you simply don't have the practice time to install several new plays. Reps on new plays take away reps (i.e are more "expensive" from a time perspective) from existing plays, so the timing of the game matters as well. For example, by the time we came down to the last game of the season, it's more feasible to add a wrinkle here and there because by that time we'd run our base stuff hundreds of times. Especially at a small school, where you have guys going both ways, you have to subscribe to the KISS principle; otherwise your kids can't play fast because they are too busy thinking.
