East Texas is very deep at the Class 3A level, and two of the very best teams in that classification will meet Friday night for one final tuneup before their respective district campaigns begin.

Harmony (4-0) hosts White Oak (4-0) at 7:30 p.m. Friday night in the ETSN.fm + Dairy Queen Game of the Week.

Both teams come into this week ranked in the latest Associated Press Class 3A poll. Harmony checks in at No. 7, while the Roughnecks are right behind at No. 8.

Harmony has been rolling all season long, defeating its four opponents by an average margin of 38 points per game. The Eagles are coming off a 63-6 drubbing of Quitman, but their signature win thus far was a 62-26 win over two-time defending 3A Division II champion Waskom in Week 2.

White Oak has relied on a high-powered offense to get through the first four games of the season unscathed. The 'Necks average 48 points per game, but were challenged last week, rallying for a 43-36 victory over Daingerfield.

Be sure to check out the White Oak-Harmony game preview Wednesday morning on ETSN.fm, follow our own Mike Graham (@Mike_ETSN) for updates throughout the game, and head back to ETSN.fm late Friday night or early Saturday morning for complete game coverage.
