You know, trying to emulate another team so the "real" team can practice against something like what they might see in the game that week. It's not garbage time, but it isn't meaningful reps in the system either.
No need to "over work" the entire team either.
If you're fine with totally sucking yewt in September, by all means, keep things EXACTLY the way they are. I understand that, things are perfect in Cougartown and there is absolutely no room for improvement.
