If you're saying 'Marner > Matthews!' based on one game against Winnipeg where they'd already clinched the division, their match-up and very clearly didn't give a f***, I don't know what to tell you.
Matthews is easily better and more valuable, but I've become fine with how much Mitch makes, he'd be the best player on every team except ours, Edmonton, Tampa, Pittsburgh, Florida, Boston, Colorado and Vegas.
He's developed a shot, but he does still have stretches where he tries to be too fancy and it does cost us.
I've been becoming inclined to think that Keefe does have a secret PP plan and he's waiting til the postseason to debut it, since the Leafs basically clinched mid-March, but if not then the PP sucking isn't on Mitch; Rielly has no shot and teams know it, and they do that p***y little drop pass instead of carrying the puck into the zone with speed.
4th in league scoring is excellent and he had an excellent season, but he's also got the most to prove. He's compiled numbers but never really been dominant in the post-season except once against Boston and they still lost.
I'm pulling for him.
