Sorry, I miss spoke.
Riverdale is in a region with a very competitive team at the top and the next three are over rated and beat each other.
In Riverdales 8 wins, 7 on them were against teams that were a combined 26-44. They beat Cookeville by 2 and lost to Blackman by 2. That indicates to me these three teams are pretty equal and not dominate by any means.
They lost to Oakland by 29.
As far as MJ goes, I have nothing but respect for a team that shutout its first 6 opponents and went undefeated.
