As a homeschool dad, I'm sympathetic to the cause of the homeschool athlete, but I agree with most of John's post. There is a distinct advantage for the larger team, homeschool or not, especially with 60 players.
Last season, I was an assistant coach on a team that played a homeschool team that had 40 players on the roster and allegedly cut 20 more after a couple of weeks of practice began. I think we only had 10 kids suited up the night we played them. We were fortunate that we were able to finish the game, and even more fortunate to be competitive in most of the game, but the experience really took its toll on some of our players. Some of our kids never returned to 100% after that game.
I am definitely not accusing anyone of cheating here, but I still don't understand how their team would qualify to fall under the Division 1 requirement for T-CAL, which this team was a member of that league. If you count all of the players they have, plus the high school-age siblings in their families, and especially those kids that tried out and didn't make the team (which are all required to be included in the "school's enrollment numbers" for T-CAL), it would seem possible, if not probable, that they could be over the enrollment limit. But that's a matter for Jason Balli and Billy Helm from T-CAL to figure out with their coaches.
Regardless, I sure wouldn't recommend any small roster team to go play a team of that size. Even with membership in a league, you need to be careful.
As for "graduation" into 11-man football, all I can say is . . . try to find a good reason to move up, especially when you're winning and dominating other teams. It's awfully hard, especially when parents and kids are enjoying the success. Especially when it is incredibly difficult to find games at the 11-man level against comparable competition, why would you pursue it? Not only that, the travel expense can be even worse. Ask SA Cornerstone or San Antonio Christian School, among other smaller 11-man teams - it's hard to find games. T-CAL has only one 11-man team - Cornerstone -so that means for a homeschool team to have to scramble to find 9-10 games on their own. If UIL teams won't play them, and for good reasons they don't, TAPPS teams are the only option. Try to find a game in October when TAPPS district play is in full swing. I'd stay at the 6-man level if I were an AD or head coach. It would make more sense to "split" a program into two or more teams and play 6-man than to go to 11-man, both financially as well as competitively. And I wouldn't be surprised if that's what happens in the near future.
Again, I'm sympathetic to the cause, but John's right: know what you're going to face before you commit to playing one of these teams.
