Box 5. Box 4. The stratifications are irrelevant when it is actual point spread in each subcategory that determines whether you finish 1st, 2nd, etc..
Assuming that the current top 4 finish as the final top 4 on Saturday (a near 100% certainty), one can make a rational argument that for any subcategory, any of the top 4 could win that category (with different probabilities). Brass could go to any of the top 4. Visual, GE, guard.
No one can make a rational argument that Crown will finish first in drums on Saturday. And I'm not talking "The Sanford Trophy" here, which is a 3-night average score.
If Crown could just be as strong in percussion as they are in every other category, Saturday evening would be almost a lock for them to win.
