The better way to schedule would be to find a conference that fits your enrollment better...
I guess when I see 3A Mac taking it to 7A Plainfield N last year, I don't see your point..
There is a better way to align the CCL, which includes five 3A teams. See post from pjjp. He lays out a very good approach which would reduce obvious mis-matches and make for more competitive games.
3A Mac taking it to 7A Plainfield N last year is an isolated game. Of course you would cherry pick one atypical example to argue the point. Hat's off to Mac for having one of the best 3A programs in the state year in and year out. Since you don't see my point, here is reality for 3A vs. 7/8A illustrating the CCL Red vs. CCL Blue (plus Fenwick) since 2012...
3A - St. Joe
2015 vs. Rita = 56-0 loss
2014 vs. Rita = 55-14 loss
2013 vs. Fenwick = 63-0 loss and BR = 63-14 loss
2012 vs. Mt. Carmel = 54-0 loss
3A - DePaul Prep
2015 vs. Loyola = 42-0 loss
2014 vs. Loyola = 42-6 and Fenwick 38-0 loss
2013 vs. Providence = 42-0 and Fenwick 40-7 loss
2012 vs. Loyola = 42-0 and Fenwick 42-0 loss
3A - Leo
2015 vs. MC = 38-12 loss
2014 vs. MC = 63-20 loss
2013 vs. MC = 59-13 loss
2012 vs. BR = 44-12 and Rita 31-6 loss
This is not good football by anyone's standards. This is 0-17 and a 41.7 point margin average.
But wait! Mac beat Plainfield North last year so none of this matters.
Again, cuddos to pjjp for his excellent conference realignment suggestion.
