A really good 1A team, particularly if they have a guy that can play in college, is going to be much better than your average 1A team with a winning record. For most 5A and 6A teams, even if they don’t have a guy that can play in college, they have enough solid guys to keep games competitive.
That’s one of the reasons Kansas keeps splitting classifications to try and avoid blowouts. There used to be 6 state champs in basketball. Now both 4A and 1A have two divisions. 3A is probably heading that way. 2A may not be far behind.
