4. Colorado Avalanche – Miro Heiskanen (D, HIFK, Sm-Liiga)

Heiskanen is arguably the best defenseman in the 2017 NHL Draft, showing skill in the offensive zone and smarts in the defensive zone.

With Tyson Jost and Mikko Rantanen likely to be top six forwards for the Avs, they take a defenseman after slipping from first to fourth overall. Heiskanen could turn out to be a top pairing defenseman with the right development and he addresses a great need for the Avalanche.
