Now, he's about to make history, etch a new chapter in the Sanderson family adventure, and potentially become the first-ever Montana-born player to skate in the National Hockey League.
"I describe myself as a two-way defenceman," Sanderson said. "I'm someone you can put in all different situations on the ice, whether it's the powerplay or penalty-kill, and can really thrive.
"Something I've really been working on, as well, is my one-timer. As a defenceman, having a bomb of a one-timer and keeping it consistent and having good aim with it is a really good asset."
Indeed.
And it's only one, of many, in the sizeable, Sanderson playbook.
The 6-foot-2, 185-lb. blueliner handles the puck and moves it exceptionally well in transition. He defends with confidence and isn't afraid to get his nose dirty. His vision, poise, and hockey IQ in all three zones resemble that of a pro beyond his years.
And, naturally, his mobility and speed off the rush can transform the attack.
As the fourth-ranked North-American skater by NHL Central Scouting, Sanderson enters the draft as the top American-born D prospect, and the second-best blueliner, overall, behind Jamie Drysdale.
He had nine goals and 43 points in 66 games last year, and has committed to the University of North Dakota for the upcoming campaign after honing his craft with one of the hockey's best development centres.
For a U.S. program that - in recent years - has cultured the likes of Noah Hanifin, Seth Jones, Zach Werenski, Charlie McAvoy and others, Sanderson has left many in awe.
"Sandy is right in that mix of the top three guys I've coached here, if not the top guy," Nick Fohr - the associate coach with the U.S. NTDP - told Mike Morreale of NHL.com. "That's still to be determined based on how he develops and where he goes, but this is something we've been talking about since last year. Somebody asked me last season where he'd fit, and I said he's already in my top five and that was as an Under-17player."
