Soderstrom, the Coyotes' first-round selection in the 2019 draft, said, "This is what you've been dreaming for your whole life, and ever since you started playing hockey."
Soderstrom brings a valuable, right-handed shot to the Coyotes blue line. He will pair with Jordan Oesterle.
"He's had a couple good practices and we want to see where he's at," Tocchet said. "That (final defenseman) spot is open right now. We're looking for who's going to grab it, and we want to give him a chance."
Soderstrom is transitioning to the smaller North American ice surface after playing most of his hockey on a larger, international size surface in Sweden. He gained some experience playing on the smaller surface during the World Juniors tournament in Edmonton, at Rogers Place, home of the Oilers.
"Obviously there's a smaller rink here, but I got warmed up during the World Juniors." Soderstrom said. "It was a good tournament; we played a lot of good teams. So, I think I'm ready for it. Battles in the corners -- it's stuff like that I need to be good at to play at this level."
Soderstrom played five games with Team Sweden during the World Juniors, registering five assists. He served as an alternate captain and was named one of Team Sweden's "Top Three Players."
Tocchet analyzed Soderstrom's transition this way:
"I think sometimes up in the NHL when things are a little more structured, it'll be a little easier for him. He knows he has to work on defending. When he's in front of the net he has to take sticks. Those are the things that he has to work on. Obviously, his first pass breakouts, (ability to) walk the blue-line and his vision is elite.
"I just told him to play his game. But be conscious of his man. Make sure he takes his man in certain situations, and just enjoy the moment."
