Welcome to the league. Coming in as a 7 seed this late in the season, being one week from the playoffs, pretty much guarantees that you will be demoted to Division 5. But don't sweat, Most teams start in D5 and move up to D4 a few seasons in. I'm not really sure why Buzzer Beater puts new teams in D4 because it not really fair to the new teams. We've had several new teams come in this season. But stick with it long enough and good things are sure to happen.
