exactly. i see them as a surprise or spoiler... on paper, i can list more than 10 teams that have far more difficulty in stunting and tumbling than star athletics... however, i think that SA will beat a good majority of them. although they don't have the full squad standing or running tumbling that I've seen on Brandon, Reign or Cali; and their stunt is fairly basic, they are consistent and do what they do very well. their routine is safer, but it is consistent and they can hit it which will help them place within the top 10.
last year Reign was my sleeper team & they won jamfest and 5th at worlds. i have a good feeling about these things!
Edited: I also, called Spirit Central the small senior sleeper.
