When I watch him, I think he's just tipping the iceberg of what he could be offensively. Will always likely be a defender first and foremost, but he can fly, has absolute howitzer shot and sneaky skill that he is just coming into.
Chara wasn't much of an offensive guy at a young age (22 points in 49 WHL games in his D+1), didn't have over 20 points until year three in the NHL or 40 points until year five. Just kept adding to that part of his game as he realized what a monster he was.
In the end, I honestly don't care if he's more than Lindholm level offensively, if he can become truly elite defensively and a physical monster. He can be a beast of a top pairing partner for Zell or Minty while "only" producing 20-30 points. But I really think there is a 100mph+ bomb that he'll start learning to love scoring with in time. This draft doesn't have surefire franchise talent after Celebrini, so give me the guy who suits our needs even on the low end of his potential, and has freak potential.
