I've always felt Vladar has talent. He's big, he's quick, he's a good teammate and not too weird for a goalie.
That said, eventually you just have to stop the puck more. He's been lights out his last 3 starts and it wouldn't shock me if he becomes a really good goalie one day. I just think the Oilers have a big need for a goalie who stops the puck regularly and right now, not one who might one day in the future.
I also think they need a stopper on the 2nd pair. Like Ekholm is on the first pair. They need a Weegar not a Vladar.
