"Practice has become kind of like a science experiment on the numerous ways we can kick a ball," Koch told ESPN.
From a Week 9 game against the Pittsburgh Steelers last season until Sunday, Koch has led the NFL with an average of 44.39 net yards per punt, according to ESPN Stats & Information. He averaged 39.03 net yards per punt from his rookie year in 2006 through Week 8 last season.
Minnesota Vikings punter Jeff Locke told ESPN "we'll look back at this and say, 'Sam Koch changed the punting game.'"
The Ravens signed Koch to a five-year, $16.25 million contract extension this past July.
