I'm going mixed on this one. The big classes (5A-6A) probably consistently put out the top notch D-1 kids. I think it's a statistical factor of larger pool of kids to choose from. This is supported by the earlier post on the number of kids from 6A and 5A wrestling Division 1. Also want to mention some of the kids are very succesful. See Bunch (ranked #1 currently), and Johnston.
Still haven't seen the post how many 1-4A kids wreslting D-1. Maybe they have a big list too.
On the other side, its a lot tougher to win state out of a 64 team pool than a 32 team pool. Overall the level of wrestling between classes is similar. You have to admit there is a lot of interclass wrestling. So I'm saying it's easier to win a 32 team pool than 64.
Also comment that possibly Norton may be the best team in state this year which is impressive.
But I think if you look over the years the 5a and 6A team state champions would have more depth so would probably beat the lower class champions.
