Love how you continue to include the rookie year. Let's wait and see how the rest of this year plays out before anointing Marner the winner. That's an awfully small gap, over an awfully small sample size for both players.
But I get it.... When you're argument is that soft, sometimes you've really got to grasp at those straws to push your narrative through.
