Parayko, who signed his first professional contract after his junior season at the University of Alaska, needed seven more classes to complete his degree in business administration and decided to take two of them while also trying to earn a roster spot with the Blues.
"People think I'm crazy for doing this, but I'm not crazy," said Parayko, 22. "I've been going to school and playing hockey for the past three years. This is nothing new for me. The way I see it, it'd be crazy not to finish my degree.
"I didn't want to put in three years of work towards something and then let it go to waste. I thought back to all the times I was battling through exams or a tough assignment and all the work I put into this, and there was no way I wasn't going to finish it."
Always a straight-A student, Parayko is taking three classes during the spring semester -- sports marketing, business continuity management and international business -- and while he and his teammates are battling the Dallas Stars in the second round of the Stanley Cup playoffs -- Game 3 is Tuesday, 9:30 p.m. ET in St. Louis -- Parayko will also be battling the books, with two finals and a term paper to finish next week.
"Hockey won't last forever," he said. "It could last one year or it could last 10 or even more, you never know, and I think it's always a good idea to have a college degree in your back pocket whenever you need it."
While his teammates might give him a hard time when he's doing his homework instead of socializing on the plane, or when he's eating dinner by himself with a table full of books, he knows this is the right thing to do.
"Not many guys from Alaska have really moved on even to pro hockey, let alone the NHL, so while the coaches expected us to give our best effort on the ice, they also expected us to do the same in the classroom," the St. Albert, Alberta, native said. "I owe it to myself to finish what I started, but I also owe it to my coaches who took a chance on me and gave me a scholarship so I could have this opportunity both in the NHL and to get a degree."
