Baltimore Ravens coach John Harbaugh didn't want to get into specifics Monday on how the team failed to challenge Wes Welker's third-down catch in the season opener. HarbaughWith the Ravens leading 17-14, Welker trapped a pass that extended an eventual touchdown drive. After the loss in Denver on Thursday night, Harbaugh said he was unaware of the situation because NBC failed to show the replay in time. On Monday, he put the responsibility of not challenging the play on his team and himself. "I just think we could have done a better job with that looking back on it, to get that information communicated," Harbaugh said. A reporter asked Harbaugh to clarify the Ravens' communication process when it comes to replays. "I think everybody understands how it works, we just have to do a better job with it," Harbaugh said. "We have to see it." http://espn.go.com/blog/baltimore-ravens
