Here is the way Cal Hi Sports sees it as of today.  As I recall, having a local school as high as number 4 in his rankings is the first time that has happened.

DIVISION III NORTH
1. (1) Marin Catholic (Kentfield) 4-1
2. (2) El Cerrito 5-0
3. (3) Cardinal Newman (Santa Rosa) 4-0
4. (8) Seaside 3-0
5. (5) Sutter 4-0
6. (6) Campolindo (Moraga) 4-1
7. (7) Bishop O’Dowd (Oakland) 3-1
8. (9) Salesian (Richmond) 5-0
9. (NR) Ripon 5-0
10. (4) Los Banos 4-1

Drops:
Previous No. 10 Hilmar lost to Modesto Christian (Modesto) 42-21.

Bubble Teams:
Acalanes (Lafayette) 3-1, Aptos 2-2, Argonaut (Jackson) 4-0, Carmel 2-1, Escalon 3-2, Hilmar 4-1, Menlo School (Atherton) 3-0, Sacred Heart Prep (Atherton) 4-0, Soquel 3-1, St. Helena 4-0, West Valley (Cottonwood) 4-0.

Race for No. 1:
Seaside is the major mover of the week after the Spartans beat Palma of Salinas 25-15. Palma, which has lost to a Monterey County school just three times in 29 years, was expected to be one of the top teams in the Central Coast Section this season regardless of division. Seaside also has a quality win this year over Soquel. No. 2 El Cerrito crushed D4 North No. 2 Valley Christian of Dublin 54-0 and will try to end No. 8 Richmond Salesian’s 26-game win streak this weekend. Salesian’s streak is the longest current win streak in the state. El Cerrito, along with No. 1 Marin Catholic and No. 3 Cardinal Newman, will all be in the CIF North Coast Section Division III playoffs. The winner of that bracket therefore looks to have almost a lock to be one of the two teams in the first NorCal D3 bowl game. If Sutter from the Northern Section and/or Seaside in the CCS are both unbeaten, the choice for the other team in that game could be difficult.
