In GA, all fall sports start before the start of the school year. That's even considering that most schools start by the 2nd week in August at the latest and many start August 1.
In looking at our schedules, it looks like ours do too. Practice starts mid-August with games starting 2 weeks later. But to complete all of the playoffs prior to Thanksgiving, they would need to either compress the schedule, or reduce the levels of playoffs. That is still risky as November weather is very similar to March weather here. Mid to upper 40s... To be honest, we have a 5 month period (Nov, Dec, Jan, Feb, and Mar) that is nearly worthless for most outdoor sports.
