Great replies so far. I was aware of the new Command stuff but didn't look deeply into it as I noticed it too close to the season starting. I think we will try it in the offseason as it looks really good once you get your head wrapped around it.
Also, this thread isn't just for 1675

Even if you have an architecture completely different than being discussed here, go ahead and post. It would be nice to have a large set of ideas for teams to be able to look at in the future.
