John Hayden is a center with many of the tools NHL teams look for in the draft. He has the size, skills, and aggressive temperament to develop into a top-nine power forward. Equally comfortable carrying the puck or finishing the play, Hayden is especially effective around the net. He does not shy away from throwing his weight around and has the capacity to be a force in the physical game. Skating is still an area in need of improvement for Hayden as well as continuing to develop his overall game.
A graduate of the USNTDP, Hayden will skate in his freshman season for Keith Allain at Yale University in 2013-14. The Bulldogs will be looking to defend their 2013 National Championship victory.
