Sanheim is a long athlete who skates really well in every direction and handles the puck well, which is clearly his biggest asset as a defenseman.
He was virtually unknown at the start of this season, as it was his first year playing in the WHL, which makes him a pretty big rarity as a first-round selection.
But his natural ability helped catch the eye of scouts, and he became the biggest riser in the draft. Seventeenth is pretty high for a kid with basically just one good season under his belt as a prospect, and there were some really talented players still on the board.
If his upside is reached, he could easily be a top-four blueliner and potentially a No. 2 defenseman who plays on both the power play and penalty kill. But it's still hard to figure out how likely it is that he will reach his potential.
