Man this degraded quickly. Also hits the nail on the head about these boards as well.
Potential is seen more valuable then a proven player in their prime. I can see the cost and team control piece of things but with the way things have been going in the league, if your that good there are no more bridge deals.
I honestly can't see in any case where Marner > McD. Marner still has work to do to reach his potential, which is not a franchise player but a good top line player. McD is already a top pairing Dman that is 28.
