It's more than that IMO, his decision making in the offensive zone has not been great, and he has not been driving the net.
He's also been caught puck watching defensively at times.
He also went through some stretches when he was not shooting the puck either.
You sir have the burgundy glasses at full power if that's all the issues you seen with his game lately.
I'm really not trying to start a MacKinnon bash session, but hes had his share of youngster struggles in 2016.
Not at all, I expected much of what you listed though with a 3rd year guy getting his first full time look at Center in the NHL.
He has to know by now though that most NHL defensemen he faces are too good to get beat 1 vs 2. Most of the Dmen he faces regularly are too good to get beat head on 1 vs 1 without going wide with speed no matter if you are a center or a winger.
