No, they didn't. The D did get blasted by UCLA on the same thing multiple times to great effect. However, outside of the comical 15-missed-tackles play in the 2nd half, they did a great job of doing a 180 and reigning in the UCLA attack. They never gave up at any point in the game and made key stops to allow us to match the Bruins score-for-score.
Which we sorta nearly did, or were doing, before our offense went into the tank. It was plain as day the playcalling errors our offense engaged in during the second half of that game. Our toss sweep game has been one of our biggest assets this season, and we didn't make use of it nearly as much as we could have. And Beck flat out panicked early on with plenty of time - nearly half the fourth quarter to go - going to an 'air it out every down' mentality as if we were down 4 with 60 seconds to go.
That lost us the game, and I might add, spoon-fed UCLA the last touchdown by handing the Bruins the ball with an already near-insurmountable lead, near the goal line.
