Arthur Kalyev is one the biggest high point totals, zero actual impact on games player I ever saw in Junior. Based on his boxscore alone, he should have been a top-5 pick in his draft year, but he fell to the early second. He's like Tomas Tatar. He'll get numbers in the regular season, but when the playoffs start? He's the last player you'll want on your team. If you took his skills and gave him Gallagher's heart & will, he'd be in the short list for best player in hockey.
I watched some of his games and you will never notice him. And somehow, he's on the scoresheet.
He'll probably have a decent career on teams that are always at the bottom of the standings and he'll have respectable numbers. But you'll never see him on championship teams barring an of God.
