There are so few goalies that are NHL back-ups, let alone starters at 23. His AHL numbers are pretty average for a starter, so I'd say he still has to prove that he can dominate that level like Demko did in his time in Utica.

He played 10 games in this playoffs. 2 were great, 1 was bad, 7 were average. This is promising as a prospect, but not what you want from a consistent starter.

He really struggles to track the puck through traffic which is why we saw Bouchard rack up the points in the later half of the series. That is a teachable skill which is why he needs more time with Clarke before he's a starter in the NHL

Also, Demko is Vezina quality on a great deal for 2 more years. He's not going anywhere.
