It's time.
Gartner is fine as a member given the standard the HHOF has set. Ideally the standard would be higher, and Gartner would miss out, but that isn't the case. I don't see a big difference between Gartner and Marleau. Gartner has a small offensive edge, Marleau has a small defensive edge.
Would you keep McDonald as a member if the standard was what you think it should be?
He finished in the top for goals four times. He had a better peak than Gartner but didn't have the same level of consistency. His era adjusted stats aren't all that amazing, and even playing in a high-scoring era, he barely made it to 1000 career points.
