"He'll still go out for important draws in penalty-killing situations when we need it, or have consecutive kills in a row," Williamson said.
Rasmussen is tied for the Western Hockey League lead with 15 power-play goals despite missing the past five games with a lower-body injury. In 50 games he has 55 points (32 goals, 23 assists), five game-winning goals and 29 power-play points.
He feels a solid second half to the season will help bolster his draft stock even more.
"I think I'm a hard-working power forward," Rasmussen said. "I like to use my teammates, get to the dirty areas of the ice. The most important thing is improving, so long as I work hard and keep improving things will happen."
Rasmussen played for Okanagan Hockey Academy bantam prep and had 87 points (41 goals, 46 assists) in 59 games in 2013-14, and then was selected by Tri-City with the seventh pick of the 2014 WHL bantam draft.
"Being around him every day for a couple years now, nothing he does surprises me," Williamson said. "Sometimes it surprises you when you realize he's only 17 years old, but he's very physically mature, skates well and gets around the ice for a big man."
Williamson had fifth-year WHL player Tyler Sandhu as Rasmussen's regular right wing.
"Sandhu is a good offensive playmaker and he and Rasmussen complemented each other well," Williamson said. "[Rasmussen] has good acceleration, mobility and strength so he covers a lot of ice and a lot of range and he's a very smart player. Put those things together and he gets a lot accomplished."
Rasmussen said his favorite player to watch on video is Mats Sundin, who spent 19 seasons in the NHL before retiring in 2009.
"I like the way he played; he had good hands in front of the net, went to the tough areas, worked hard and skated really well for a big man," Rasmussen said. "If I can be a little bit like him, I think that'll be good."
Williamson said he anticipates Rasmussen having a long, productive hockey career.
"He's going to get drafted high, but regardless of where he goes he's going to continue to improve and he's going to have a long career," Williamson said.
