UNIVERSITY PARK -- The white -- not unlike the Penn State defense -- was everywhere, covering every nook and cranny of a roaring Beaver Stadium.
  What made the difference on this night, though, were the splashes of yellow that frequently dotted the green turf.
  The Nittany Lions' 31-10 payback defeat of Notre Dame -- before a crowd of 110,078, the second-largest in Beaver Stadium history -- was as much about the mistakes the Fighting Irish made as the number of big plays Penn State (2-0) made. The momentum that had never favored the Nittany Lions during last season's 41-17 loss in South Bend swung both ways for much of Saturday's game, but the home team did the most with it.
  "People don't say it, but that was the only game we really got blown out," Penn State linebacker Sean Lee said of last year's game. "We wanted revenge."
  Lee and the rest of the defense, blitzing Irish freshman quarterback Jimmy Clausen on nearly every passing down and stonewalling a mediocre Notre Dame rushing attack, earned that revenge with another dominant performance. Derrick Williams, Chris Bell and Anthony Morelli made highlight-reel plays that led to or resulted in points, and the Nittany Lions' offensive line and tailback Austin Scott wore down the Irish defense in the second half.
  As if all that wasn't enough, Notre Dame couldn't get out of its own way.
  The Fighting Irish (0-2) racked up 14 penalties for 97 yards -- only 47 fewer than they managed in 58 offensive plays. Whether it was false starts by the offensive linemen -- in which the crowd played no small role -- face-mask penalties or a bizarre personal foul on a punt return play that might have swung the momentum to Penn State for good, it seemed that every key play involved or soon followed a yellow flag.
  "It was miserable," Notre Dame coach Charlie Weis said. "Even though we practiced for this, and a couple of those false starts penalties can be attributed to noise, it's still a lack of concentration. We had 13, 14 penalties and when you're not playing a very efficient offense yourself and you add the number of penalties in there, it doesn't bode well for any type of momentum."
  The Nittany Lions, who did not commit a penalty in the first half, were whistled seven times for 65 yards in the second half, but most came after they already had a tight hold on the game.
  "Basically what it comes down to is nobody wants to run on Monday," said Penn State linebacker Jerome Hayes, grinning. "Penalties equal extra sprints. The whole coaching staff preaches no penalties, play fundamentals, play assignment football, and we were able to do that today."
  Hayes was involved in a penalty that was perhaps the game's turning point.
  Notre Dame, up 7-0 after Darrin Walls returned an Anthony Morelli interception 73 yards for a touchdown on Penn State's initial possession, had the Nittany Lions pinned deep in their own territory after Morrice Richardson sacked Morelli for a 13-yard loss on third down. Jeremy Boone punted to the Notre Dame 44-yard line, where Tom Zbikowski corraled it with a fair catch.
  The Irish's Travis Thomas, however, who was tangled up with Hayes on the ground after trying to reach Boone, took several cheap shots after the ball was long gone, directly in front of an official, and received a 15-yard personal foul penalty.
