Orange County Register takes a look at the Blackshirts and the threat they pose to USC’s green QB.

Nebraska led the nation in sacks in 2005, and they would love to make USC quarterback John David Booty a tad uncomfortable in his second career start Saturday.

They might have the right man for the job. Defensive end Adam Carriker is an All-America candidate who stands 6-foot-6 and weighs 295 pounds. He had 9.5 sacks in 2005.

“That big fellow is really a load,” USC coach Pete Carroll said.

“If you can rush a team with four guys, that makes everything difficult,” Carroll said. “They don’t have to show anything. They can disguise their coverages and all that.”

Booty had a solid first game against Arkansas, but he could get a stiffer test against Nebraska’s defense, which returns seven starters on a unit that finished in the top 30 nationally.
