Dobson was No. 5 among North American skaters in NHL Central Scouting's final ranking. Wahlstrom was No. 7.
"All we can say is we're glad they were where they were when we picked," general manager Lou Lamoriello said. "So we feel very good about it. You never know when it comes to the draft, everybody has a little different focus, but these were two players we had very high."
Wahlstrom, an 18-year-old right wing, had 83 points (40 goals, 43 assists) in 54 games with the United States Under-18 National Team, leading it in points, goals and assists. He had 45 points (22 goals, 23 assists) in 26 games with Team USA in the USHL.
"Prolific scorer," Lamoriello said. "He's got great hands, very talented."
Dobson, 18, scored 69 points (17 goals, 52 assists) in 67 games with Acadie-Bathurst this season, leading them in assists and ranking second in points. He had 13 points (three goals, 10 assists) in 20 playoff games to help Acadie-Bathurst win its first Memorial Cup championship.
