MTL offense was abysmal the last two years.
And MTL defense was loaded in youngsters.
So basically, Matheson was used way too much and I have the impression MSL gave him carte blanche offensively.
So he played like a loose canon, a loose canon that was used too much and became teared down, he looked tired mentally. So his decision making was impacted.
Take away 2-3 min from his average 25, plus give him a proper defensive zone system (MSL man on man defensive system is a mess), and Matheson will be a solid all around Dman.
As he has it all, the size, the skating and the skills.
If he was used properly, he could be a solid 40ish pts defenseman that can do it all.
