"When you pour as much time and effort into an opponent going in and expecting to win, and you don't perform as well as you could have," said DeRuyter, "there's disappointment, there's frustration, there's anger."
DeRuyter was not happy with any part of the Bulldogs performance, pointing to missed opportunities on defense.
"We missed too many tackles in the run game," DeRuyter said. "We did some decent things on defense but we didn't force enough takeaways. We lost the turnover battle."
He also credited Boise State's defense with creating just enough havoc to throw off the high-powered Bulldog offense.
"They did a good job of re-routing receivers, they did a good job of pressuring Derek," said DeRuyter. "When you have some doubt in there it doesn't look right, and clearly we had that happen on Saturday and we have to get that cleaned up this week."
If there is a light at the end of the tunnel for Fresno State, it's that they return home to Bulldog Stadium for Saturday's Mountain West battle against Wyoming. The Cowboys are 1-5, but DeRuyter says that number is extremely misleading.
"Their record is nowhere indicative of what kind of football team we're getting ready to face," DeRuyter said. "Although they're 1-5, the last couple of weeks they've gone down to the wire."
Kickoff for Saturday's Fiesta Night is set for 7:30 pm Pacific, and will be televised on Comcast SportsNet California.
