The Coyotes did not have a selection in the first three rounds.
"To be able to walk out with some players, even though we weren't picking high in the draft, we were still able to acquire (five)," he said. "I'm very proud of the staff."
The Coyotes selected five players in total: Defenseman Mitchell Miller in the fourth round (No. 111); forward Carson Bantle in the fifth round (No. 142); forward Filip Barklund in the sixth round (No. 173); forwards Elliot Ekefjard (No. 192) and Ben McCartney (No. 204) in the seventh round.
Miller was the first selection under Armstrong's regime. The GM was pleased with the pick.
"He's a two-way defenseman," Armstrong said. "I think one of the things I like about him is that the puck always seems to be on his stick. He's a little bit undersized, but what he brings to the table is an ability to produce points and move the puck. The number one thing about him is he's a puck mover."
Miller was one of 39 players invited to USA Hockey's 2020 National Junior Evaluation Camp, used as an evaluation process for selecting the U.S. National Junior Team to compete in the 2021 IIHF World Junior Championships. Miller leaves Wednesday for Plymouth, Mich., and the national camp.
Armstrong wasn't directly involved in the drafting process, but he followed through on the tradition of phoning each selection, including Miller, who said Armstrong told him he's looking forward to their meeting in Arizona.
"You try to make sure that you welcome them into the organization and show them a little bit of love." Armstrong said. "It's a big day for them. Sometimes you get to do that in a normal draft in person with these kids."
Armstrong doubled down on the team's plan to send each player a memento to honor their selection, something he said "they've earned the right for" on Tuesday.
"We're definitely going to get a jersey (for them)," he said. "A swag bag, and we've got a special picture (we're taking) for them Thursday. I can't really get into what that is," he added with a grin.
Along with congratulating each player, Armstrong quickly began to coordinate.
"What we try and do is get them set up with our development coaches," Armstrong said. "We make sure that we know where they're playing, what's around them, who's coaching them, and try to make them feel as comfortable as we can.
"We let them know, 'Hey, you're a Coyote, and this is what's in store for you. We're really excited about having you.'"
