For a long time I had 2 teams of my own, and was co-coaching anywhere from 1-3 others at the same time. When 3.0 came out, I dropped to 2. Then I dropped to 1. I have since increased to 3 of my own, simply because there is too much "dead time" with only 1 team.....AND its hard to gather data and try new things with only one team that you care about. So, I have 2 teams that I care about and one that is really just experimental. I'll drop that experimental team in a couple of seasons.
