Groulx is a strong, well-rounded, two-way center…good, but not great, skater…needs to improve his first step…high motor, always keeps his feet moving…rarely caught out of position…provides a lot of grit, determination and skill…excellent ability to maintain puck control in high traffic areas…uses his strength, skilled hands and agility to be very difficult to defend…a threat to drive the net but can also go stretches of playing on the perimeter too much, being content to just dish the puck from the outside…he thinks the game at a high level, and can put on a show with his nifty stick work and creativity…shoots the puck hard, and accurately…owns a deceptively quick release and isn’t shy to show it off when available…strong awareness of when to support his defenders in loose puck battles and where to go… adept at tracking down pucks out of scrums…provides good pressure on the backcheck…displays a strong effort in his own zone as well as his ability to create scoring chances…a solid prospect that could be the complete package with high upside at the NHL level.
