Not to be picky, but if the question is 13U, then we have to be precise.
To Goblue's point, 12U teams have it easy. A 14U team can carry girls that are officially 13 and 14 without penalty, as they are classified as the older age group. Same goes with 12U teams, and all the even numbers, for that matter.
To respond to wvanalmsick, I absolutely agree, there are some younger teams that are holding their own in the 14U world. The point of the first question is probably that those teams that are true 13U can return every player for next year - as 14U players.
I am guessing that the Ice team is a true 13U. The Buckeye Heat team is a true 13U. Probably some of the other organizations are too - so who are they?
I can say that the Buckeye Heat team has been playing .700+ ball this year. But we have been primarily playing a PONY/USSSA schedule, with ventures into some of the smaller ASA/NSA venues. Did just fine at GAPSS - going 3-3 and making it into the final 12.
The team will be a contender next year at any 14U venue.
