While the Combine does not feature any on-ice components, there is still plenty to be gained for the teams' medical staffs, scouts, and front office personnel as they gather valuable intel on each participant. And for the players themselves - all of whom are still teenagers competing in Europe, junior or college hockey - it is their first taste of the scrutiny and pressure that comes with a career in the National Hockey League.
"You want to perform very well off the ice and you want to show physically that you're strong, mentally that you're strong and mature, and kind of impress these teams, leave them with something that you remember," said Charlie McAvoy, who attended the Combine in 2016, just a few weeks before being selected 14th overall by the Bruins.
The centerpiece of the Combine is, no doubt, the physical testing. From endurance to strength, every area of the prospects' fitness is measured and examined under the microscope of trainers, doctors, general managers, scouts, and the media.
"It's interesting in the weeks leading up to it," said Carlo. "You really dial it in to the off-ice training. I think at times you do things that you wouldn't necessarily do to get ready for it and it kind of shows you how much you care about this sport and how much you want to make it.
"During those couple weeks, it was grueling, but it was a time where I proved to myself how bad I wanted to be in the NHL."
