RICHMOND, Va. -- A day after getting a better look at film of the Washington Redskins sloppy preseason debut in a 23-17 loss to the Atlanta Falcons, coach Jay Gruden said penalties and the teams running game will get more attention.The Redskins were whistled for 14 penalties for 123 yards and ran the ball 24 times for just 79 yards in the loss. Their top three running backs, Matt Jones, Chris Thompson and Keith Marshall, had no yards on eight carries.Yeah, penalties are an issue, man, Gruden said after practice Saturday in sweltering heat on Fan Appreciation Day. Its a very important part of the game -- offense, defense, special teams and penalties, man, and turning the ball over.We looked at them extensively today and make sure we get them corrected because those things -- you can be as skilled as you want to, be as prepared as you want to, but if you commit penalties, youve got no chance.Some of the penalties -- namely holding calls on tackles Morgan Moses and Takoby Cofield -- could be blamed for hampering the running attack, but guard Spencer Long said even this early in preseason camp, thats no excuse.It was just sloppy, Long said after a practice in which the defense dominated. Obviously, theres no excuse for that. Weve got to clean up our play, and that will come with time as well.I could sit here and say its a result of Game One, but were pro football players and theres no excuse for that. Hopefully we learned from the film and learned how to not draw holding calls, not jump offside and get it cleaned up.The Redskins worked extensively on their running game Saturday. Seeing that turn into results when the Redskins face the Jets in their second preseason game would be nice, Gruden said, especially Matt Jones, now the top tailback after Alfred Morris signed with Dallas.Were not going to panic after the first preseason game, but we also understand that these games, you are what you are based on what you put on the tape, Gruden said.We have got to make sure we continue to work on it and get better at it. Thats all you can do. Our backs have got to continue to see it, but we have got to give them more opportunities.With Matt, it would be nice to get him two, three, four carries in a row to get a rhythm going and see how he does then. That will be our intent next week -- to try to get him going and see how he does.Thompson said being in a real game situation could account for some of the problems the Redskins encountered in Atlanta.And Gruden credited the Falcons defense, but even while admitting the defense came more pumped up to practice on Saturday, Thompson said the offense needs to take the sessions -- or their mistakes -- more seriously.We cant make mistakes in practice and think, `Oh, its just practice. Well fix it once the games come around, he said. We have to understand that we have to get those things fixed now.Gruden also took some of the blame for letting mistakes happen in practice.Were going to coach them up, he said. Were going to work on it and make sure we do our best not to let it happen again.---Online: AP NFL website: www.pro32.ap.org and AP NFL Twitter feed: www.twitter.com/AP-NFLCheap Air Max 270 .

Free-agent big man Al Horford has agreed to terms with the Boston Celtics?on a four-year max deal worth $113 million, his agent, Jason Glushon, told ESPNs Ramona Shelburne.Horford revealed he was heading to Boston earlier Saturday on his Twitter account.The deal, with includes a player option after the third year and was first reported by The Vertical, came as the team was meeting with prized free agent Kevin Durant?on Saturday.As a nine-year veteran, Horford was eligible for 30 percent of the new $94.1 million salary cap and will earn roughly $28.2 million in the first year of the deal.League sources told ESPNs Brian Windhorst that the?Atlanta Hawks final?offer was five years and $136 million, which was less than a max deal. The sources added that, with Horfords departure, the Hawks will halt trade talks regarding Paul Millsap.The Celtics had room for two max-contract free agents this summer, and they met with Durant on Saturday night. Adding Horford to a 48-win team makes Boston a contender in the Eastern Conference and might give them a shot at attracting Durant.Horford, an unrestricted free agent, has played his entire nine-year career in Atlanta, which drafted him third overall in 2007. The four-time All-Star averaged 15.2 points, 7.3 rebounds and 3.2 assists per game last season.After the Hawks were swept by the?Cleveland Cavaliers?in the playoffs for the?second straight year, Horford stressed just how much he had enjoyed playing in Atlanta and that the team still can winn with some improvements to its current core.dddddddddddd.There are a lot of things that we need to address, Horford said of talking to his family and advisers. But the biggest thing for me is I feel good here. I have a great relationship with Coach [Mike Budenholzer]. That is important to me. And my teammates.Atlanta is a city that welcomed me from the first day, he added. Im very grateful for people that have always been real positive toward me and my family. I feel good. I feel like the way the team is going, I feel like we can win here.Horford was the topic of trade rumors at the deadline, with the Celtics reportedly among the interested teams.The 6-foot-10 center, who turned 30 in June, was expected to draw interest on the free-agent market for his ability to shoot from the perimeter.Last season, Horford shot a career-high 256 3-pointers after taking a total of 65 3s in his previous eight seasons.I probably got a little away from the post this year trying to expand my game and do different things, Horford said. That is a point of emphasis, that I will try to be better in the post and be able to put the ball down a little more on the floor. Being able to drive a little more. Even though I had some strides in that area this year, I think I can be even better at that.Information from ESPNs Ohm Youngmisuk and Chris Forsberg was used in this report. ' ' '
