Hayes is a rugged, hard-working, 6-4 and 210-pound power forward. Although Hayes is not afraid to mix things up, this season he has been able to strike a balance between his physicality and playing with discipline. He uses his size, strength, and reach to great advantage, particularly in tight areas and is difficult to move off of the puck. One attribute that has had scouts really taking notice of Hayes is his shot. He possesses one of the hardest shots in all of college hockey and he shoots with great frequency. He also has great finishing ability. What separates Hayes from many other top scorers, particularly among those with big bodies, is how little energy he expends when creating or finishing plays. His skating and puck movements often times look effortless, and he effectively utilizes his given time and space. Hayes moves really well for a man his size and skates with long, powerful strides. His leadership and ability to set the tone of a game were invaluable assets for Minnesota State-Mankato and they are qualities that Hayes could one day bring to his pro team.
