Harbaugh took full advantage to jump on the Patriots a little bit more on Tuesday morning during a radio appearance on Baltimore's 98 Rock.
The coach was originally asked about the mess that the Saints are in, but he was still able to bring it around to center on New England.
"Isn't there a part of you that says, you know, if a guy can get away with it, like, you look for the edge any way you can get it, right?" one of the hosts asked of Harbaugh.
"You know, the funny thing about that is that in the end, everything is brought before the light of day when it's all said and done," Harbaugh said. "If you look at New England, no matter whether those things had any impact on whether they won their championships or not, they got asterisks now. They've been stained.
"To me, it's never worked. … But if you're cheating, in the end, you're gonna get discredited."
The comments aren't exactly said with a ton of venom (hear the audio below), but it is a little bit more interesting considering the source. Following the AFC Championship game, a game the Ravens loss to the Patriots, Baltimore kicking coordinator Randy Brown questioned some of the in-stadium scoreboard management at Gillette Stadium.
"The scoreboard was one down behind, the entire last three plays from what we understand," he told 94 WIP on the Tuesday following the AFC championship. "I don't know," Brown responded when asked whether or not the Patriots intentionally caused the problem, but did add, "I don't think you can rule anything out in New England, can you?"
To Harbaugh's credit, though, he dismissed any talk about scoreboard malfunctions.
"We knew what the down and distance were on our last series," he said. "The scoreboard was not a factor for us. Any suggestion that the wrong down information was a deliberate effort to affect the outcome of the game is nonsense."
The Ravens and Patriots will meet in Week 3 on Sept. 23, a Sunday night game in Baltimore.
