Geekie helped drive Winnipeg's offense last season with 70 points (24 goals, 46 assists) in 63 regular-season games and 11 points (three goals, eight assists) in 15 playoff games.
Like most players Geekie's age, he's still polishing his game but said he knows what he must do to get to the NHL after signing a three-year, entry-level contract on July 18.
"I wouldn't say I'm slow by any means," Geekie said. "When I get going, I'm a decent skater, but again, you can always get faster, you can always get stronger, you can always get smarter. I was always told that IQ and vision you can teach early, but not late. Skating, you can teach early and late."
Although Geekie sustained an undisclosed injury that limited him to 45 minutes of ice time during development camp, he said he expects to be healthy for the start of training camp in September.
"I absolutely want to try and crack the team, that's every 18-year-old's dream," he said. "I've got to get a little faster, have a little more pace to my game. I'm just excited to see what happens."
Geekie said he won't be disappointed, though, if he returns to the WHL, and it's unlikely the Coyotes would elevate him to the NHL prematurely.
"He had some dominant performances with his size and ability and just his energy and how hard he works," Armstrong said. "For a big guy, there's a little bit of inconsistency he's got to work on. I think that's a maturing process to where he can be good like that every single night.
"But he has what we love. He's got the size and he plays physical, and he's got the skill."
Not long from now, Geekie wants to experience what Arizona is like in January and February, not just July and August.
"It's been a pretty easy fit to make the transition," Geekie said. "Definitely a lot more responsibility, but I'm excited. It's all part of growing up and being an NHL player."
