Three highly regarded teams put their perfect records on the line and took losses, shaking up our south Los Angeles County rankings. Coaches can only hope lessons were learned and teams are better because of it. (Note: Last week's rankings are in parentheses.)
1. (1) Long Beach Poly (3-1)
A total of nine rushing yards in 18 carries won't get it done against the elite. The Jackrabbits had their chance on the road but came up empty. Last week: Lost to Mission Viejo, 17-12. Next: at Compton, Friday.
2. (3) Bishop Amat (3-1)
Senior running back Jalen Moore had 191 rushing yards and a pair of scores a week after his eye-opening 303-yard, five-touchdown performance. Last week: Beat Damien, 28-7. Next: vs. Cathedral, Friday.
3. (NR) Loyola (4-0)
Boise State-bound Chaz Anderson had two touchdown catches and, for the most part, contained one the area's most explosive receivers. Last week: Beat St. John Bosco, 28-14. Next: at Upland, Friday.
4. (2) St. John Bosco (3-1)
The Braves couldn't dig themselves out of a 21-point hole, stumbling for the first time this season. An acrobatic 44-yard touchdown by Bryce Treggs was the highlight of the night. Last week: Lost to Loyola, 28-14. Next: at La Habra, Thursday.
5. (4) Carson (1-2)
The Colts suffered their second defeat of the year but there were some positives, mainly the fact that they led in the third quarter despite not getting a major contribution from Darreus Rogers. Last week: Lost to Santa Margarita, 39-21. Next: vs. Mission Viejo, Friday.
6. (5) Lakewood (3-1)
We're just four games in and senior Brock Dale, who transferred from Peninsula, has already more than doubled his touchdown passes from a year ago. Last week: Beat Leuzinger, 55-0. Next: at Long Beach Wilson, Friday.
7. (8) Charter Oak (3-1)
As expected, senior quarterback Travis Santiago had yet another monster statistical showing (353 yards of total offense) but the test proved too big for the Chargers. Last week: Lost to Rancho Cucamonga, 21-13. Next: vs. Santa Fe at Pioneer HS, Friday.
8. (7) Serra (3-1)
Ricardo Rijo (151 receiving yards) caught three passes and all went for touchdowns, helping the Cavaliers overcome the absence top target Raymond Ford (ankle). Last week: Beat Banning, 27-7. Next: at Narbonne, Friday.
9. (6) Narbonne (1-2)
A second straight loss for the Gauchos, who posted yet another gutsy effort away from home. But, if we've learned anything, it's that they're serious contenders in the City Section. Last week: Lost to Tesoro, 22-13. Next: vs. Serra, Friday.
10. (10) St. Paul (3-0)
Swordsmen quarterback Paul Telles averaged more than 36 yards per completion on his way to a total of 219 and two touchdowns before putting it on cruise control. Last week: Beat Garfield, 31-8. Next: vs. Ayala, Friday.
Dropped out: West Covina (10)
Five more, in alphabetic order: Claremont (4-0), Dorsey (3-1), Gahr (4-0), St. Francis (3-0), West Covina (3-1).
