I think any of Green Hill, Cookeville, or Lebanon could win the district.
Green Hill has good wins over Beech and Blackman in non-league and already a home win over Cookeville.
Cookeville has an early season win at Stone Memorial.
Lebanon’s best win so far is at home vs Gallatin. They do have a head scratching loss at Riverdale.
Lebanon is the only one I’ve seen play and I don’t know if they have enough besides Jarred Hall to win the district this year. They really miss Yarin Alexander this year. At this point I’d say Green Hill wins the regular season title.
