Not saying Green is going to be great, but I'd be very surprised to see him go later than round 3 in the draft. And that's not me loving Green, that's just what happens when you're 6'3 and have skill, you get drafted early. Normandaeu and Foster will be picked late in the draft.
Sometimes, you have good players with limited size, and you love their hockey sense and think they're better hockey players than bigger, more hyped players. For instance, I probably think Jake Todd is a better hockey player than Peddle if you base your evaluation purely on hockey sense and skill, but Peddle will go top 10 and Todd will go round 3. That's how it is. Teams draft projectable players, and size is a great factor in that. Green could probably step up in the Q at 16 and be okayish, because he has the physical assets to do so. Normandeau may never play.
