Saw both Wizard 10u teams and they were both tough! Good solid coaching and their young girls could play some ball.
If they are returning alot of their core players, then they will be a strong force to deal with.
Couple others I saw that seem strong was the Ohio Danger team and the Miami Sting (like mentioned above). Havent able to see to many due to only having 4 tournaments this season for 10u.
Our youngest dd has 3 years left of 10u ball so I will see many,many changes in the 10u landscape through out. Amazing many of the girls she faced this year and next year, she will probably not see them again.
