I said in the other Eichel thread that he’s one of those guys who tends to look better than his numbers and I think Pettersson tends to be the opposite. He can be quite flashy at times but a lot of what he does involves moving the puck out of harms way and into more dangerous areas efficiently and he’s been more productive than Eichel the past two years despite not always looking his best.
That said, his disappearing act in the second half last year was concerning even with the injury explanation. He’s now had two half-season where he became a shell of himself due to nagging injuries where either he can’t find other ways to contribute or the physical problems seem to get in his head. I’d be a little less concerned about the coming season/playoffs with Eichel instead imo.
