Makarov, of course, had joined the Stanley Cup-champion Flames in Moscow to start the second half of their 1989 Friendship Tour (they'd opened with two games in the Czech Republic).
"Being in Russia of that time certainly made us appreciate Canada, I can tell you that,'' reminisces Roberts. "I know if I saw one more bottle of Pepsi or plate of rubbery Chicken Kiev …
"And what really struck me were the pop machines. You'd put in a coin and you'd take a drink out of a cup, then place the cup back in the pop machine for the next person to use. Everybody shares the same cup!
"That was only one of the things I saw that just blew me away."
Another eye-opener arrived the night Roberts and Nieuwendyk were invited to Makarov's apartment for dinner.
"Sergei, remember, was the 'Wayne Gretzky of Russia','' Roberts reminds you.
"And this place was small.
"I think it worked out to 300 square feet per person, so 900 total square feet. We had to go up in twos in the elevator to get to this penthouse apartment. But in that 900 square feet he had this amazing trophy room of all the crystal he'd won during his career.
"I remember this room, a tiny little room, but it had a ton of crystals. That's when I think I fully realized all that he'd accomplished in his 20s to be who he was at 30.
"The other thing I remember was his wife, Vera, brought in fresh vegetables. Because Sergei was the 'Gretzky of Russia' he got a little piece of land outside Moscow to grow his own vegetables. So she'd gone all the way out to get the vegetables for us, to make us feel welcome.
"I was, what 23, then? So it was kind of cool to be able to learn about his life in Russia at that time."
The hockey tutoring began almost instantly, involuntarily, almost by osmosis.
"There was nobody who could take the puck down the ice like Sergei Makarov,'' reminisces Roberts. "Nobody. He didn't even seem to move. He had that way of swaying without really lifting his feet, and people would just sail past him.
"Just an amazing, amazing player who accomplished so, so much before he got here. Then everyone was p--ed off when he won the Calder. But those were the rules at the time.
"And people might not believe this, but he was a really funny guy. I loved to listen to him talk, express himself. He was serious, sure, but get a few beers in him and you saw this other side. He told us some crazy stories about (Viktor) Tikhonov and playing for Soviet Red Army.
"We had some great times with Sergei Makarov."
Another such time is just around the corner, Nov. 14th in Toronto at the 2016 Hockey Hall of Fame induction festivities.
"I'm going to take part in that weekend with Joe,'' says Roberts. "It'll be fun. We'll get an opportunity to see Sergei again, talk over old times and congratulate him.
"He deserves it.
"What a player."
