There was no need for any that when the defenceman could continue growing academically and athletically at one of the world's most renowned learning institutions, which happens to be a 45-minute drive from his hometown of North Easton, Massachusetts.
The 6-foot-2 rearguard, playing for the Harvard Crimson in the Eastern College Athletic Conference of the NCAA, is feeling right at home in the brick infrastructure of Harvard University and making the absolute most of the opportunity he has at the esteemed establishment.
With its 5.4% acceptance rate and only 21,000 students, getting into the foremost Ivy League school is a feat in itself. For Marino, going to the supreme learning centre in his home state didn't seem as though it would be a reality until later on in high school, but it's a special sentiment for the Bay Stater who bleeds Boston.
"I really didn't really picture it until in high school, then I thought it was possible," said the freshman, already with one goal and five assists in 19 games played so far into his first NCAA season.
"Being from Massachusetts kind of makes it more special and you appreciate it a little more, playing for a team from Boston and especially a prestigious one."
The captivating architecture and bustling nature among the school's scenic campus grounds - which most people only get a glimpse of in the movies - is admittedly inundating for the first-year but Marino is beginning to acclimatize to the historic setting and its reputation.
"Everywhere you go, there's something," said Marino. "There's tourists all the time walking by. It's kind of overwhelming sometimes but you don't really think about it that much, just kind of walk through campus like a normal college."
You never know who you could be brushing shoulders with while walking the halls, either. With alumni including former United States president Barack Obama, as well as technological innovators Bill Gates (who dropped out) and Mark Zuckerberg, some of the students attending could be the world's next trailblazers. It might not always be easy to spark conversation with peers of such high intellect but it's definitely something Marino has enjoyed.
