Koch shanked two 26-yard punts during the first half of a 26-23 win, a consequence of attempting to angle them too close to the sideline. He finished with a season-low 34.2 average.
"I picked a little wider angle on those," Koch said. "I tried to pick a really wide angle hoping it would come back. I took a slide step, too wide of an angle, which caused that. I've been hitting the ball well. I've been hitting it really well.
"I felt really confident going out there, but took too wide of an angle and I think it was just one of those things. The form was good. It was uncharacteristic. Nobody's perfect. Everybody is working to try to get better."
"In the long run, I think it will be good for me," Koch said. "I've been pretty pleased with what I've been doing in the first four games. This kind of makes you look at things differently and gets you more humble. You focus on your technique and the things you need to do to get it right, the fundamentals."
On Monday, Ravens coach John Harbaugh expressed no concern about Koch going forward and regarded the game as an aberration.
"That was very un-Sam like," Harbaugh said. "Those are two shanks that he usually doesn't have. We try to punt to the sideline.
"If you hit it a little bit off-center, that's what happens: real short punts. We've asked Sam to do that a lot and he's done a great job of it. On those two, it didn't work out so well."
