Holloway - like Makar - is a rarity, having graduated from the AJ to the NCAA ranks, and flourishing in his freshman campaign after adjusting to the pace of the much-ballyhooed Big-10 program.
In 35 games, the 6-foot-1, 203-lb. pivot had 17 points - but with five of his eight tallies coming in the final 10 spins of the season.
It was only a matter of time.
"The AJHL is a great league, but the NCAA was such a big step up for me," Holloway said. "Guys are so much bigger, stronger, faster, and when you combine all three, it took some getting used to, for sure.
"I'm a guy who likes to have the puck on my stick. I love to make plays. So, there definitely wasn't as much time out there. Sometimes in the AJ, you can hang onto the puck a little bit more, that extra half-second, but in the NCAA, you kind of have to know what you're going to do with the puck before you get it.
"That was definitely a big adjustment, but over time, I started to feel more and more comfortable, more confident with the pace, and I think that showed in my game.
"It's like any other step up in competition. You have to believe in yourself and your abilities, and trust in what got you there."
Holloway, whose father - Bruce - played pro in the 80s and even suited up for a couple of games with the Vancouver Canucks, certainly has the pedigree.
He's the No.12-ranked North American skater by NHL Central Scouting, and after one quick look at the highlight reels, the star-studded package he brings to his year's class is glaringly obvious.
His vision with the puck and ability to read plays in transition are especially strong, while his speed, size, and defensive acumen make him a threat to produce at both ends of the ice. He loves the physical side of the game, too, and prides himself on winning puck battles, but has the poise and the grace to make plays under pressure, and dazzle crowds with his creativity and instincts around the net.
He's the ultimate in modern-day, game-breaking power forwards.
A first-round lock.
Where, exactly, he slots in is anyone's guess, but anywhere from picks 10 through 20 seem likely and with the Flames holding the 19th-overall selection, the local product could potentially don his hometown colours on the night of Oct. 6.
