Maatta is a good defenseman. He gets shit on a TON because of his inability to make turns quickly. His straight line speed is decent, but not great. But he's slow at turning, which will get him caught more often then fans like. And unfortunately the optics of this look terrible. Everyone remembers when he f***s up because they see someone blowing by him (Bobby Ryan in 2017 is still a goal I vividly remember to this day).
However, Maatta has a very good IQ, and usually uses his smarts to keep himself in good positions. So while his skating looks bad (and there's definite issues there), his overall effectiveness is very good. For example in the POs last season, he was only on the ice for 2 ES goals against - one of which should have been blown down on an obvious penalty.
If Maatta could skate like Dumoulin, he'd be seen as a Lindholm caliber of defender, and a clear cut good #2/3D. With his skating issues, he's somewhere in the 3/4 range depending on his day to day games. Basically he's usually someone you only notice when things go bad... but you really remember those mistakes, while his overall stats are good.
