Are you talking about the same Collinwood team that got beat by the 8-14 (3-5) Wayne County team a few days ago?
Collinwood and Summertown are the clear favorites to advance to sub-state out of Region 6, but Loretto, Richland, and Cornersville will go down swinging.
Moore County and Cascade are the clear favorites to advance to sub-state out of Region 5, but Houston County, McEwen, and Nashville Christian aren't bad either.
With that in mind, Summertown and Moore County are the best teams and should be the 2 that advance to M'Boro, but any of the others mentioned also have a shot if not a good chance as well.
