From my limited information, I'd probably put Lakota East above Beavercreek, but there's no doubt those are the top two teams on paper.
Yeah, Creek is always very solid, but Mikesch carried them in matches with good teams when I saw them play the past two years - and he's gone now. I expect Beavercreek to be able to fill in with more solid players, but you can't replace Parker. Creek has a solid program with a ton of kids playing volleyball top to bottom (down to 6th grade at least) - so they'll be fine in the long run.
Lakota East just seems loaded because so many of their contributors were juniors last season, so I give them the #1 spot. After this season, they probably drop below Creek again though.
