Week Zero High School Football Preview: Bolsa Grande vs. Laguna Beach

Where/When: 7 p.m. Friday at Laguna Beach High.

Key Matadors: Sr. QB Andrew Guillen (53 of 133 passing for 520 yards, three TDs, and eight INTs; 16 carries for 109 yards and one TD); Sr. RB/OLB Elian Gallegos (30 carries for 104 yards and one TD; eight tackles); Jr. LB Daniel Alvarez (22 tackles and two sacks).

Key Breakers: Sr. QB/FS Curtis Harrison (163 of 288 passing for 2,100 yards, 21 TDs, and nine INTs; 141 carries for 298 yards and 10 TDs); Sr. WR/SS Adam Armstrong (25 catches for 430 yards and four TDs; 448 kickoff return yards; four INTs for 52 yards); Jr. WR/FS/K Sean Nolan (29 catches for 345 yards and four TDs; four INTs and one fumble recovery; 38 of 42 on PATs and 6 of 10 on FGs).

Breakdown: Breakers coach John Shanahan looks to build on a successful first season at Laguna Beach. Last year, he became the program’s third different head coach since the Breakers posted an undefeated regular season in Mike Churchill’s final year at the helm in 2012. Shanahan delivered with the program’s first winning season since then and a run to the CIF Southern Section Division 13 semifinals…Several key players are returning for the Breakers, including quarterback Curtis Harrison and dynamic senior Adam Armstrong. Harrison showed dual-threat capability, making him dangerous in short-yardage situations…Ryan Blaser caught 19 more passes than any other Breaker last year, but his graduation means that Armstrong will undertake the role of Harrison’s primary target. He made four trips to the end zone last year, including a team-long 80-yard touchdown. Armstrong also had four interceptions and took the bulk of the kickoff return opportunities…Laguna Beach won the road matchup in their series with the Matadors, 47-18, to open the 2016 season. This year should not be much different, as Bolsa Grande averaged just 11.6 points per game.
