Jaguars' offensive coordinator Dirk Koetter claims that the team's offense will improve. The Jaguars are 24th in the NFL in yardage, 25th in passing offense and tied for 26th in scoring after three games. "No question," he said of an improvement. "I'm guaranteeing it. This week." He believes the team has receivers that can get open deep. "If you brought those wideouts in here and said, 'Can you get behind the defense?' every one of them is going to say, 'Yeah, I have been. They haven't hit me,'" he said.
