The Trojans ran the ball effectively and took advantage of key Eagles turnovers, hanging on for a 30-22 upset victory.
"We saw some things that were open and we just took advantage of it," Osso said after University ran for 306 yards to post its first victory of the season. "Literally, that's all it was. [Trojans senior] Tyler Stanek is a phenomenal wide receiver, but we saw there were a lot of holes open in the run game."
University senior Chastin Gammage did most of the damage, running for 128 yards and two scores. But Ryan Kuo (70 yards) and quarterback Zach Christy (52 yards) also contributed mightily.
"To be honest with you, a little bit," Estancia Coach Mike Bargas said when asked if he was surprised at the efficiency of Uni's running game. "They had a good little scheme against us. It just takes the momentum to swing, and then we're kind of grabbing ourselves."
Estancia (2-1), ranked No. 5 in the CIF Southern Section Southern Division poll, was denied its first 3-0 start since 1999. The Eagles got into the red zone twice in the first half but had no points to show for it after a pair of interceptions. One occurred in the back of the end zone, the other at the Trojans two-yard line.
The game was scoreless at halftime. The Eagles did strike on the second play of the second half on Robert Murtha's 59-yard touchdown run. Murtha finished with 185 yards rushing.
But the unranked Trojans (1-2) answered back on their first possession of the half when Gammage found the end zone from 13 yards out. A fumbled snap on the next possession hurt Estancia, as the Eagles' third turnover gave Uni the ball at the Eagles' 25-yard line. The visitors eventually scored again on a three-yard touchdown run, taking a 14-7 lead.
