Dahlin said he was 11 years old the first and only time he met Hedman during a summer hockey camp in Modo (SHL), and recalls how all the kids looked up to him. Hedman played for MODO prior to being drafted.
"He's such a good two-way defender who can play the power play and kill penalties," Dahlin said. "He can play in any situation and is amazing to watch."
Dahlin played and took part in many media scrums in 2017-18, including regular-season and playoff games for Frolunda, and with Sweden in international tournaments.
Hedman was impressed how Dahlin was the youngest player by seven years on Sweden's roster at the 2018 PyeongChang Olympics.
"It's tough not to hear about Dahlin back home," Hedman said. "I know he didn't play much for Sweden at the Olympics but he was amazing for Frolunda and at the world juniors. If you compare it to the [2017 IIHF World Junior Championship], I think he was a more complete player. He played more minutes and he's a smooth skater, always in the right position.
"The few games I've seen him play, he makes the right decisions with the puck and you can tell he's got a really good winning mentality and he won't take no for an answer."
Dahlin won best defenseman at the 2018 WJC with six assists, a plus-7 rating and 25 shots on goal while averaging more than 23 minutes a game for Sweden. Hedman sees one distinct similarity between he and Dahlin.
"He gets frustrated if it doesn't go the team's way and that's how I am," Hedman said. "You want to do well, you want to win games and he's got that attitude that I really like. That's the way he plays and the way he moves on the blue line is just a treat to watch.
"Whoever gets him in the draft is going to be very lucky."
Hedman said Dahlin won't ever forget his NHL Draft experience.
