Beau Yap extended his hand, turned it back around and stuck his pointer finger directly in his own chest.

Make that the figurative chest of every member of the Hawaii defense after a 37-27 loss to San Jose State on Saturday night at Aloha Stadium that dropped the Rainbow Warriors to a woeful 0-5.

"I don’t even know where to start. It was a very disappointing loss because the offense did a great job tonight from the previous (Fresno State) game," said Yap, a junior defensive end. "But honestly this game was all on us, all on the defense. We lost this game."

Numerous long gains by SJSU translated directly to long faces in the Hawaii locker room. The Spartans gashed UH repeatedly in a 27-point first half, which featured six plays of 16 or more yards by the visitors.

Defensive coordinator Thom Kaumeyer was stone-faced and frank after his charges allowed a season-high 534 yards of total offense.

It flat-out came down to effort, he said, particularly on numerous missed tackles.

"You get what you do, you get what you put in," Kaumeyer said. "There’s no puzzle in this game. It’s not a magic trick. It’s not a mystery. What you do and how you play is what’s going to happen. That’s why any team, no matter what, can beat another team. It’s whoever plays well is who’s ready to go. They came in here ready to play."

And by extrapolation, UH did not. SJSU seized control with 24 unanswered points to end the first half, which included touchdowns of 61, 35 and 39 yards.

But perhaps most jarring to the UH "D" was Austin Lopez’s 44-yard field goal to open the game. UH came in confident from a strong second half of play against the FSU Bulldogs. But the Spartans, led by quarterback David Fales, moved the ball swiftly with gains of 11 and 15 yards on their first two plays from scrimmage, setting the Rainbow Warriors back on their heels.

"It kind of shocked us because we thought we were riding high off the last week, shutting (FSU) out in the second half," Yap said. "I thought we went in too big-headed and they took advantage of that."

No one aspect of the defense was at fault, the Kamehameha product said. All shared blame equally.

"Every position had mistakes. Starting at the D-line, we got cut out of our gaps. We weren’t in our right gaps. Linebackers weren’t filling right. DBs weren’t covering our zone or whatever it was. It just came down to every aspect of our defense fell apart at times, and they took advantage of it."

Two second-half interceptions by defensive backs were not enough for the unit to redeem itself. Fales was not efficient — he finished 16-for-35 — but he made the requisite throws for a road win in totaling 318 yards. Running backs Tim Crawley and Jarrod Lawson combined for 182 yards.

There was optimism to be found after home losses to USC and Fresno State, both ranked teams at the time. It was harder to conjure up a silver lining this time as UH heads back on the road to UNLV next week.

"Obviously, defensively, I didn’t prepare our guys well enough," Kaumeyer said. "We played horrible in the first half; it’s probably the worst half of football we played this year. We bounced back in the second half, but we missed tackles. When we needed to make a play, we didn’t make it."

Linebacker TJ Taimatuia led UH with nine tackles, tying for game-high honors, including two for loss. Yap had 11⁄2 tackles for loss and two quarterback hurries.
