Defenseman Brendan Guhle, 21, could push for a top-six spot this season. Last season, his first as a professional, he had five assists and averaged 18:06 of ice time in 18 NHL games. He has an offensive game the Sabres would like to add to their defenseman group. "He brings an element to our back end there just with his speed," Botterill said. "Nowadays in the National Hockey League, teams backchecking so much, so hard, the back pressure, you have to have your defensemen be able to create offense, and he certainly brings that dynamic there."
