Stromgren spent the 2020-21 season with three different clubs in the Modo system - the U18 and U20 squads, and their HockeyAllsvenskan affiliate. He also appeared in 11 games on loan with Ornskoldsvik in Sweden's third tier, HockeyEttan.
This was actually by design. With the pandemic creating all sorts of chaos and limiting action for many of hockey's top prospects, Stromgren saw an opportunity to play in a variety of leagues, with different opponents and responsibility in key situations.
But, most importantly, reps
In total, he played 38 games in the two men's leagues, including 27 in the Allsvenskan - Sweden's equivalent to the American Hockey League.
His nine points (3G, 6A) were the highest total of any under-18 player in that league, after leading his amateur club with 10 goals and eight helpers in only 14 tilts.
"It was a really, really good year," Stromgren said. "I probably would have played more with the U20 team, but they closed up early. But then, to get a chance with the men's team, play some big minutes and really learn from some of the older guys there?
"Amazing.
"The biggest challenge - and I learned this right away - is that you have so little time. You really need to capitalize on your chances because you don't get as many as you do in the lower levels. You need to be focused, dialled in, all the time. When you get the good advice from the older guys, it helped a guy like me to handle the pressure of what was a pretty big step up in competition."
Stromgren was recently traded to Rogle BK. His goal, next year, is to play full-time in the SHL before making the transition to North America.
To do that, he's looking to bulk up so he can properly handle the rigours of the pro game.
"My strength is all I'm focused on right now in the off-season," he said. "On the ice this year, I had some defensive parts of my game weren't as good as I wanted them to be, so I'm working really hard at that.
"And, honestly, I think improving my size, my strength, will help me a lot in those areas.
"If I get a bit bigger, my game will get a lot better, too."
