I think it depends on your fantasy scoring. I had both in a league that rewards goals 2x to assists so I had to drop Luke. If it's a keeper League, keep Luke. I don't know if they'd ever go so far as to replace Dougie on PP1 bc of his shot, but Keefe is a wildcard too. Did he give players a long leash in Toronto, bc Luke is going to need a long leash with his turnovers.
