The biggest thing for Matt this year is going to be consistency. He needs to be a 70+ pts player. The only way you can do this is if you are consistently putting up numbers. He can't have 10+ game stretches where he doesn't score a goal, he is too talented for that garbage. A lot of this falls on him, he needs to have his head on straight from day one, and he can't let himself get inside his head when things aren't going perfect. He is way too hard on himself and gets down too easily and it affects his game in a negative way.
Another thing I never want to see again is putting 4th line caliber players with our #1 center. I mean last year one could argue that he could have easily had another 10-15 pts had he not been saddled with players like Talbot, Caron, Mitchell etc. for over half the year. Hopefully we now have enough talented top 6 players to consistently give Matt top 6 caliber wingers. Between Iginla, Tanguay, Rantanen and Grigorenko we should have plenty of options so that players like Mitchell never sees top 6 ice time again.
I expect Matt along with MacKinnon to be the guys on offense this year. Anything else in my opinion is a failure on their parts, they are just too talented to not be big time offensive threats every night. Teams should have to worry about how they are going to limit Duchene and MacKinnon. Last year they didn't have that worry. This year needs to be different.
