Don't know much about Cumberland though they have been very sucessful this year. One mentioned earlier that they were more guard oriented with one post.
My opinion is that Shelbyville is much too strong with it's AJ/JA combination inside to be bullied around inside. JA's presence and determination is stronger than anyone is giving credit. The Buchanan girl, also a post, cannot be overlooked. She provides muscle with excellent shooting ability. The guards are good and can get the job done even though they are not as strong as Shelbyville has had in the past. I have seen nights where the guards were on fire and destroyed teams guarding the inside.
Even if a good game plan is worked, the bench is so strong that they eventually wear you down. A strong defense and a rentless in your face press at times causes turnovers that even strong teams have a hard time dealing with. Most of the nights they manage to get this done without many fouls.
Don't rule out the coaching. Shelbyville is loaded with coaching talent and this could be the difference. I have not seen any of their coaches panic and become distracted during the game. They are always in control and steady at the helm. This means alot to the girls on any team and also Shelbyville. Yes, they work the refs like a surgeon knowing when to pursue an issue and knowing when to cease.
Shelbyville can be beaten as has been proven in their district. I think Shelbyville is peaking at the right time and this can cause probems for the teams they will play in the future.
If they stay focused-potential state champion
