GREEN BAY, Wis. — Packers coach Mike McCarthy is pleased with his decision to switch to a 3-4 defense, after only one preseason game. New defensive coordinator Dom Capers showed off the new scheme against the Cleveland Browns in the opener, and it paid dividends with a shutout victory. The Packers enjoyed Sunday off after forcing four interceptions, racking up three sacks and holding the Browns to 191 yards in a 17-0 victory Saturday. Two weeks after last season’s disappointing 6-10 finish, the Packers fired five defensive coaches, including former coordinator Bob Sanders, and their strength coach. They brought in Capers and a new staff. "The decision was made in January. I made it with a clean, conscious mind,” McCarthy said. "I like what I’ve seen so far. I’ve said it before, time and time again as I stood up here: I like the way Dom Capers has come in here. He’s pulled the defensive staff together. The players have responded.” Right from the start, Browns quarterbacks Brady Quinn and Derek Anderson couldn’t do much against a blitzing linebacking corps that includes A.J. Hawk, Brady Poppinga, Brandon Chillar and Aaron Kampman. "We threw a decent amount of stuff at them,” Hawk said. "We blitzed a little bit and got pressure and sacks on the quarterbacks. We have a lot of different things we can do in this defense.” And they have a lot more big names who will play in it soon. Starting cornerbacks Charles Woodson and Al Harris had the night off, and first-round pick, defensive tackle B.J. Raji, signed on Friday and wasn’t ready to play. Former first-round pick Nick Barnett (knee) also is close to returning to practice, and reserve Desmond Bishop looked sharp, rushing Anderson into a throw that was picked off by Tramon Williams. Bishop also had a sack and an interception.
