Krug, a defenseman, has taken on a more physical role in the playoffs, and is hoping a good-luck undershirt from Marchand also helps his offense against the St. Louis Blues in the Stanley Cup Final.
The Bruins lead the best-of-7 series 1-0. Game 2 is here Wednesday (8 p.m. ET; NBCSN, CBC, SN, TVAS).

"I don't know. I just remember on the road one day, my shirt was missing and he happened to have an extra one in his bag with his number on it," Krug said after practice at TD Garden on Tuesday. "So I've been rocking it for a while in hopes that some of his skill and determination would rub off, and hopefully it does."
Krug had 53 points in the regular season, including an NHL career-high 47 assists. He has 12 points (one goal, 11 assists) in 18 games in the Stanley Cup Playoffs. Marchand set an NHL career high with 100 points (36 goals, 64 assists) in the regular season, and has followed it up with 19 points (eight goals, 11 assists) in 18 postseason games.
Marchand, a forward, is also known as an agitator, and in the playoffs, Krug has taken on more of that role. In a four-game sweep of the Carolina Hurricanes in the Eastern Conference Final, Krug drew a penalty from Hurricanes captain Justin Williams and frustrated him with several big hits.
