As a younger player, Greenway was more hesitant to use his frame to get to the dirty areas. He never had to. Blessed with tremendous size, Greenway also boasts hands and ability of players who are much smaller.
But as he's gotten older and matured under the guidance of coach David Quinn at BU, Greenway has discovered where he's going to one day make his money.
"I'm definitely a lot more comfortable in my game," Greenway said. "I've kind of figured out what my assets are, what gives me success in a game, so I've just been finding ways to perfect that and perfect my game more as a power forward down low who brings pucks to the net. I'm just going to fine tune that and I think the rest will fall into place."
Despite an opportunity to turn pro following a sophomore season in which he scored 10 goals and chipped in 21 assists, Greenway is heading back to Boston for another year of seasoning.
"I kind of want to win a lot more championships there. I've done what I wanted to and I just kind of want to find a way to create more offense for myself and be more of an impact player when I come in here," Greenway said. "I don't want to be average. I want to come in and have an impact for a while as soon as I can, so going back to school for one more year, that's what I'm going to do."
The Terriers were one of the top teams in the country last season, but lost a ton of talent to graduation and early pro signings. It will give Greenway an opportunity to hone his leadership skills and play every weekend knowing he is the likely target of an opponent's defensive game plan.
It's a challenge Greenway said he welcomes with open arms.
"I don't think I've had that role for a long time, and I'm kind of happy to do it.," Greenway said. "I'm going into the year, I think I've really got to lead this team, and like I said, I want to win a lot more championships there. If we're going to do that I've got to lead the team and have a pretty big impact."
With NHLers no longer headed to the Olympics in PyeongChang next February, there's also the belief that Greenway could be a vital cog for Team USA's hopes for its first Olympic Gold Medal in men's ice hockey since 1980.
While the thought has certainly crossed his mind, Greenway said he doesn't want to get too far ahead of himself.
"Honestly, it's probably in the back of my mind, yeah, but I'm just looking to have a good start for BU next year," Greenway said. "If I start the year on a good pace, I think hopefully I'll have a chance for the Olympic team."
If things go as planned, and Greenway has a strong start to the year in Boston. If he is selected for Team USA and plays in the Olympics. And if he helps the Terriers to a Frozen Four at the Xcel Energy Center next April, a pro contract is the likely next step for the big power forward, who likely could play high-level professional hockey right now if he wanted to.
"For me, there really shouldn't be a player that can defend against him," Bombardir said. "If he's on his game, and he's willing to play the game the right way, the way that he needs to play it, there should be not many guys [who can stop him], certainly at the level he's playing at now, and even the guys at the next level. He'll be tough to defend against."
