In Notre Dame's first two games of the season, the Irish turned the ball over 10 times.
It resulted in two losses to start the year.
The Irish still struggled with turnovers over the next two games but it got better, and as Notre Dame won four straight games--the turnovers were all gone.
Until Saturday night.
With the Irish a yard away from tying the game in the 3rd quarter against USC, Dayne Crist fumbled and Jawanza Starling returned it for a 99 yard swing to give the Trojans a two touchdown lead.
Notre Dame had two more turnovers in the 4th quarter.
"We thought we were past that," Kelly said after Saturday night's game. "That's the toughest part is when you think you've moved past that kind of self inflicted wounds, to come back and have those hit you again, it's disappointing."
Kelly says you can't beat good teams playing just one half of football and turning it over at the 2 and 27 yard lines.
"To turn the ball over in the ridiculous fashion that we have, I just... it just makes me crazy," Kelly said. "I just don't understand how something so easy can come out the way it does."
Notre Dame looks to bounce back Saturday when they welcome Navy to the Stadium for a 3:30 kickoff.
