Not much is needed to ratchet up the intensity of the rivalry between Ivy League foes Harvard and Yale. However, South Shore Kings '97 right defenseman and 2015 NHL Draft prospect John Marino might have helped do just that.

The North Easton, Mass. native switched his commitment from Yale to Harvard recently. Ranked No. 63 by NHL Central Scouting in the Final Rankings for the 2015 NHL Draft, Marino is a slick-skating, mobile defender who is terrific in transition and has a very good stick.

His de-commitment from Yale was reportedly partially spurred by the departure of Bulldogs assistant coach Dan Muse who left the program to become the new head coach of the USHL's Chicago Steel.

Harvard head coach Ted Donato and associate head coach Paul Pearl have been hot on the recruiting trail after a stellar season that saw the Crimson win the ECAC Hockey Tournament and advance to the NCAA Tournament for the first time since 2006.
