Good job missing the entire point. He didn't say being flashy means you aren't good. He's saying you can be a great defenseman without being all flash. Which is true.
It's also not about pumping his tires and tearing down other defenseman, it's about recognizing the fact that just because Juolevi hasn't made the NHL yet, only TWO years after being drafted, doesn't make him a bust or that we should start worrying about him.
