GREEN BAY, Wis. - The brief scuffle at Packers practice turned heads in the crowd. The dropped ball by a receiver during an offence vs. defence security drill drew roars from defenders. The team has grinded through off-season workouts with a work ethic that coach Mike McCarthy says is one of the best hes seen during his nine years as head coach in Green Bay. The energy is up. "Im not saying the other groups werent mature," McCarthy said. "It just seems like this group is further ahead than weve been, and you can sense the energy." Caveat: Its June, still more than six weeks from the start of training camp and three months from the start of the 2014 season. Almost every team feels good this time of year. The Packers, of course, have a championship pedigree. Confidence that comes with winning three straight NFC North titles, and just a few seasons removed from winning the Super Bowl. "The work ethic is very high. This group is really extremely competitive, in tune. Our new training environment has been unbelievable. It has put us so far ahead of where weve ever been, so I think with that brings more confidence so theres just a sense of maturity," McCarthy said. Changes on the coaching staff brought some new perspective. Quarterbacks coach Ben McAdoo left to become the offensive co-ordinator of the New York Giants, while outside linebackers coach Kevin Greene left to spend more time with family. Sam Gash is the new running backs coach after Alex Van Pelt slid over to replace McAdoo. Winston Moss is the assistant in charge of all linebackers now, not just inside linebackers. Former Illinois and Florida head coach Ron Zook is now an assistant special teams coach. Green Bay hopes the defence will be improved this year with the addition of Julius Peppers and the anticipated healthy return of linebacker Clay Matthews from an injured thumb. Eddie Lacy has a full year of seasoning now as the lead rusher in a talented backfield that complements Rodgers. The 2011 NFL MVP, for one, likes the spunk hes seen on the practice field. "I love it. I love the energy, I love the passion. There will be those altercations in training camp. When guys remember this is a professional environment, not a personal environment, then you wont have any issues in the locker room," Rodgers said. "But every now and then you have to stir it up a little bit, you have to make some changes." Rodgers said he also likes the changes he has seen with new personnel and new coaches. "Its a natural progression. And when you have some new players theres always going to be stuff like that, guys getting used to this tempo," Rodgers said. "Sometimes guys dont like getting tossed down a little bit, and you need to work it out." Fringe players anxiously looking for a roster spot shouldnt get too overly worked up. Jobs arent won in June, McCarthy said, when practices are tailored to highlight agility and playing in space. But McCarthy likes some of the intangibles that he has seen so far. "I think youre seeing more player interaction as far as what goes on on the field. Guys self-correcting, and a lot more pro-active as far as sharing information," he said. "Those are good things. I see more of it this year." Note: The Packers signed rookie free agent Shaun Lewis on Tuesday. Lewis, a 5-foot-11 linebacker from Oklahoma State, tried out at Packers rookie minicamp in May. He had 73 tackles and three interceptions last season for the Cowboys. __ Online: AP NFL website: www.pro32.ap.org and www.twitter.com/AP_NFL ___ Follow Genaro Armas at http://twitter.com/GArmasAPJon Duplantier Jersey .

The person spoke on the condition of anonymity because the hiring has not been announced. The team was expected to make it official on Thursday. The move ends a long search that began with the last-place Cubs targeting New York Yankees manager Joe Girardi, only to be denied a shot when he decided to stay put. Instead, the Cubs are hoping Renteria can help develop their young players and lead them to their first championship since 1908. He replaces Dale Sveum, who was fired after two seasons. The Cubs went 66-96 this season and finished at the bottom of the NL Central. A former major league infielder, Renteria spent the past six years on the Padres staff and had been their bench coach since 2011. Before that, he coached and managed in the San Diego and Florida Marlins organizations. Renteria also managed Mexico in the World Baseball Classic in March. The Cubs are counting on him to get the most out of young players such as shortstop Starlin Castro and first baaseman Anthony Rizzo, along with prospects such as Javier Baez, Jorge Soler, Albert Almora and Kris Bryant.dddddddddddd. The lack of development by young players on the roster was a major sticking point with Sveum. And with more young players on the way, the front office decided it was time for a change. The Cubs were 127-197 under Sveum and finished in last place for the first time in seven years. They had targeted Girardi, a Peoria, Ill., native and Northwestern product who played for them. But the former catcher signed a four-year contract worth up to $20 million to stay with New York through 2017. That forced the Cubs to look elsewhere. Besides Renteria, they interviewed former Mariners and Indians manager Eric Wedge, Rays bench coach Dave Martinez, former Nationals and Indians manager Manny Acta, former Diamond-backs manager A.J. Hinch, and Brad Ausmus, who was hired by the Tigers on Sunday. They were also interested in talking to Boston bench coach Torey Lovullo. But according to reports, the Red Sox invoked an agreement banning Cubs president Theo Epstein from hiring any of their employees over a three-year period. ' ' '
