I'm at a similar place.
It's not a coaching issue nearly as much as it's a player issue. The same things keep happening regardless of coach. Lack of focus, laziness, failing to move their feet, failure to execute the simplest of plays. They aren't good enough, for one (and that's the overarching issue), but these issues make the problem much worse.
I also would change to Torts just to make the players' lives a living hell for their concentration lapses and inconsistent effort. And because this team is so boring that Torts would at least provide some form of entertainment.
And I'm ready to continue with a scrap and rebuild. I don't think everyone needs to go, but their oldest players do. And some of the younger ones, too.
