Marietta validated its first-ever preseason No. 1 ranking in the opening week of the Georgia high school football season. Callaway, also No. 1 in preseason for the first time, slipped up in Alabama while taking on a larger-classification program.

Marietta, the No. 1 team in Class AAAAAAA despite a 5-6 record in 2018, beat Rome, 48-14, in the Corky Kell Classic after quarterback Harrison Bailey, a Tennessee commitment, threw five touchdown passes. Rome was ranked No. 2 in AAAAA and fell to No. 6.

Marietta will play St. Joseph's Prep of Pennsylvania at home this week in a game between teams ranked in the top 25 nationally by USA Today and MaxPreps.

Callaway lost 10-7 to Opelika, a Class 6A school from Alabama. The new No. 1 in Class AA is Rockmart, the 2018 state runner-up. Rockmart beat county rival Cedartown 31-12. Defending AA champion Heard County lost to LaGrange, 24-9, and dropped to No. 9.

The largest jump was taken by Lovett, which entered the Class AAA rankings at No. 5, after a 30-29 overtime victory against previous No. 6 Greater Atlanta Christian.
