"The frustration was evident in Jaguars guard Uche Nwaneri's voice as he sat at his locker folloing the Jaguars' 28-3 loss to the Philadelphia Eagles on Sunday. He spoke politely, but forcefully as he searched for answers to a game that featured the fifth-lowest offensive output in Jaguars history. It was the third-lowest under coach Jack Del Rio and the first time since Dec. 26, 2004, that the Jaguars had three or fewer points at home. On that day, Jacksonville lost to the Houston Texans 21-0. "This game was a big disappointment for us," Nwaneri said. "It's frustrating because you put in so much hard work. We know what kind of work we put in during the week. Film study and practicing. That's from the heart." History aside, the task at hand for Nwaneri and his fellow offensive linemen was to help fix that. After two solid outings in which quarterback David Garrard was sacked only three times, the Jaguars allowed six sacks for losses of 51 yards. By contrast, the Eagles, who came into the game as the NFL's leader in sacks allowed with 11, allowed only three sacks for 24 yards. Four of the sacks allowed by the Jags came in the second half as they tried to dig out of a 14-3 deficit. Eben Britton and left tackle Eugene Monroe knew they had tough matchups ahead of them. The second-year players faced two top-tier defensive ends. Monroe faced Pro Bowl end Trent Cole for much of the game and Britton, who has been battling leg injuries since training camp, lined up against first-round draft pick Brandon Graham. "I'll just say I didn't have the best day I could have out there," Monroe said." http://jacksonville.com/sports/foot...gles-carve-beleaguered-jaguars-offensive-line
