Kos is the type of player who could carve out an NHL career one day because he knows his strengths and how to play within them. He’s a big guy who moves well and can effectively play a meat-and-potatoes style of hockey. He’s quick, heavy and determined on the forecheck, applying a lot of pressure and forcing more turnovers and steals than your average forward. Plays the game with high levels of awareness, focus, intensity and determination, and that helps him overcome middling amounts of skill. Looks solid in the cycle, moving the puck around heavily when it’s on his stick and applying pressure on his opponents to prevent them from clearing the zone. Seems to track offensive transition play well enough, finding times to rush it up the ice himself or send stretch passes to his teammates. Has an impressive understanding of how to play without the puck, reading where the play is going and inserting himself to steal the puck or break up opposing possession. Does a really good job on the penalty kill of keeping the puck deep in enemy territory. Doesn’t look out of place playing center, at least in small doses. Has that chippy edge to his game and doesn’t shy away from contact or dirty areas. Has a good motor, which helps him stay involved in the play. Seems to have good natural athleticism, but his movement on the ice is a work in progress. Needs to improve his agility and balance, as he struggles with pivots, crossovers and direction changes. He’s heavy and slow with his stickhandling, almost beating the puck around. He also can’t do a whole lot with the puck even when he gets it in a dangerous spot, he just doesn’t have that natural feel for it. Hard to tell if his shot is a weapon because he can’t get it away easily enough. If he dedicates himself to becoming a bottom-6 defensive specialist he could become a valuable player at the sport’s highest level.
