He most definitely was - chipping in to the tune of 18 goals and 28 points during the regular season before adding two more snipes and four points during the playoffs - but Niemeläinen insists there's still plenty of progress to be made.
"What I talk about with him is focusing on balance and strength when it comes to one-on-one situations and getting in front of the net - one-on-one battles for the puck and strength. That's one thing, then it's focusing on the first two or three strides when you push off and start skating. He wants to be as explosive as possible," said Niemeläinen, a former goaltender in the Finnish ranks who played under Lehkonen's father, Ismo, before going on to work under him as a conditioning coach. "Those are the exact things that we feel he needs to get better at when it comes to the NHL."
Lehkonen is certainly in agreement there.
"I've got to work on everything. I've got to get stronger. I've got to get faster. I've got to be more versatile," said Lehkonen, who typically spends five days per week in the gym in addition to skating with his father two to three times each week. "I've also got to get more physical and stronger in my legs so I can win those one-on-one battles during games. I know I'm still young and I know I have a lot of things to improve. It's a good challenge for me, for sure. I've just got to make sure that I'm ready when training camp starts."
To help Lehkonen take that all-important next step, Niemeläinen is putting him through a rather unique workout regimen.
"It's hard to compare what we're doing to any typical weight training. It isn't a conventional system," said Niemeläinen, before expanding upon some of the key facets of the SSL program. "Basically, the machines that we have allow people to change direction in squatting-type movements very quickly. We're combining that with a lot of smaller and bigger weights to get Artturi's nervous system to act at a high level."
