Yes, true nothing is guaranteed. But it stands to reason those stunts are more likely to hit when the team is comprised of more skilled, experienced and coached athletes. Just the other day I watched a video of my daughter from two years ago. Compared to where she is now I could not believe how much better she has gotten. Outside of tumbling entirely her performance level, stamina, jumps, technique, overall tightness, and strength are not comparable and it just would not seem right for her to be on a team two levels lower than her current one.
