I mean he's given up 4.8GA/60 at ES in his time in Columbus. That's not roughly average for that team. It's by far the worst on the team for any player. He also has seen extremely sheltered minutes and spent a lot of time with the one ice tilter Columbus has in Jenner. He's actually been significantly worse in Columbus defensively than he was in Winnipeg.

Just look at those numbers. He's a -2.5GA/60 in his time in Columbus. That's shockingly bad.
JFresh charts aren't in any way valid advanced stat models. Look at the data. That tells the real story. But yes, even in JFresh models which don't account for zone starts and account for special teams (Laine plays PP) he's still bad. What you see in those charts is a player who is below average offensively at 5 on 5, which I would debate as well. He's essentially making hay on the PP. Exactly like Kuzmenko which has been my contention.
