So the question of this poll is: who is inherently more valuable? Cale seems to be the best defenseman in the league and McDavid is the best forward, so who--in a hypothetical sense--holds greater value in your eyes? Value is another way of saying 'who is better', but is also an assessment of age, contracts, positional importance, career achievements to this point, intangibles, and all the rest. I look forward to a constructive and civil discussion on this one.
