Penn State coach Bill O'Brien is defensive about his defense.

O'Brien stuck up for defensive coordinator John Butler after a historic defeat that saw the Nittany Lions allow the most points surrendered by the program.

Just this season?

Nope. Try 114 years.

Not only that, but a program built as "Linebacker U" has turned into "U Get to Score," because of a leaky defense that has allowed 40-plus points in three straight games.

Time to regroup? For sure. But O'Brien also says it's time to lay off laying the blame at Butler and the defense.
