I'm sorry, I just don't see what difference it makes. Preseason is preseason. Coaches know what they need to get out of practices (which are decidedly more important), and--whether we want to admit or not--preseason games can upend seasons before they even start due to injuries. We see it every single year.
We're going to have to be patient and let the process play out. So what if we're still learning and gelling in September? It's going to happen anyway, and a quarter or two in largely meaningless preseason games isn't going to change it. Fool yourself that it makes any type of substantive difference if you want, but it's the camp, the practices, film time and all that other stuff that happens over time that makes the real difference.
