“I don’t think a lot of people know much about him,” Timmins added. “He’s a guy that hasn’t played on the (Russian) national teams.

So we tried to take a step forward a year earlier, draft him and then sign him.”
You don't need to SPECIFICALLY say HIDDEN GEM to say..hidden gem. He was unknown. Didn't play on russian national teams. Hence HIDDEN. And if he wasn't drafted, he would be chased by A LOT OF TEAMS AND THEN YOU GET IN LINE WITH ALL THE OTHER 30 TEAMS!!! Hence GEM.
