Besides establishing a comfort zone for his wife, Nikki, and four-month old Kamdyn, Braxtyn, 2, and Ryan, 7, Koch has made an imprint on the football field.
After six games for the first-place Ravens, Koch is averaging 43.9 yards per punt to rank 10th in the AFC and 17th overall in the league. Koch, 24, beat out veteran Leo Araguz during a training camp competition and hasn't looked back ever since.
"He's got a big leg," long snapper Matt Katula said. "He's hitting the ball with a lot of confidence."
Not only did Koch average a career-high 48 yards on seven punts with two placed inside the 20-yard line in a win over the San Diego Chargers, but he earned a rare distinction with his ability to tackle.
Koch, which is pronounced "Cook," leveled Chargers punt returner Eric Parker with a hit that launched Parker airborne and left him on the ground for a few minutes.
"That was so much fun," Koch said. "I miss that aspect of the game because I haven't been able to do that since high school. Everybody likes it when the kicker gets the hit. I hope I can do that again sometime."
Drafted on special teams coordinator Frank Gansz's recommendation after he set a Cornhuskers single-season record with a 46.5 yard average as a senior, Koch has emerged as a solid replacement for former punter Dave Zastudil, who signed with the Cleveland Browns during free agency.
With a long punt of 60 yards and 11 downed inside opponents' 20-yard line, Koch has blended distance and hang time.
"I just think Sam's doing a great job," Katula said. "It's all about timing, and he gets the ball out of there as fast as Dave did. He's very calm, very collected and he doesn't get too up or down.
"You don't want to ever be arrogant, but it takes confidence in your abilities. Everyone knew what he did in college, and that has translated into the NFL."
Koch has roughly two seconds once Katula snaps the ball to catch it and get the ball off his foot ahead of the defense.
On 37 punts, he hasn't come close to having one punt blocked and has a net average of 37.4 yards with one touchback.
The low point for Koch was a 10-yard shank out of bounds on national television in a loss to the Denver Broncos, which earned him a sideline tongue-lashing from Billick.
"I need to do better than that," Koch said. "That obviously wasn't the greatest punt, but everybody makes mistakes."
Baltimore invested a three-year, $1.13 million contract in Koch, who cemented his status ahead of Araguz by averaging 51 yards on five punts in the third preseason game against the Minnesota Vikings.
"I knew I had some big shoes to fill with Zastudil gone and them bringing in Leo, who has a lot of experience," said Koch, who has doubled as the holder for kicker Matt Stover's 10 perfect field goal attempts. "I knew I had to show them. There was a lot of pressure put on me, but I was up to the task. Now, I'm going to do everything to prove to them that they made the right decision so I can play and live here for a long time."
