Riverdale could sweep it.. definite possibility. Between Siegel and Cookeville, Siegel would be the team to possibly beat Riverdale (even with their giant loss to Blackman, I think they will be better prepared to play a team like Riverdale). Its not likely, but it could definitely happen. That would definitely make things very, very interesting if Siegel could pull off the tie or upset. Cookeville hasn't played the "strength" of the district yet, with Blackman, Riverdale, and Siegel left on their schedule and their loss to Oakland doesn't help them out much...
My prediction:
1. Riverdale
2. Blackman
3. Siegel
4. Oakland
5. Cookeville
6. Lebanon
7. White County
8. Warren County
