Valiev is a dynamic skating defenseman. He has offensive ability and is a strong stickhandler. He also displays an edge to his game and is willing to drop the gloves to protect teammates.
Valiev impressed at Toronto's prospect camp, earning an entry-level contract and attended the Maple Leafs' main camp before being returned to Kootenay for the 2014-15 season. Now in his second WHL season with the Ice he also represented Russia at the 2015 World Juniors. Valiev's combination of size, skill and combativeness suggest he can be an effective top pairing defenseman at the NHL level one day. The key to him reaching that level will be his consistency.
