While Mrtka isn’t a particularly punishing player, he’s an active and aware defender. He scans for threats, ties them up, and rotates well. Though he lands the occasional big hit, his physical impact comes through his ability to absorb contact, win retrievals, and deny space. With possession, Mrtka’s no slouch, either. He makes tricky passes off the wall on retrievals, joins the rush, and manages space well at the top of the zone. -EliteProspects 2025 NHL Draft Guide
