Except he's been like this his entire career, not just this year.
There's a certain level of luck to injuries, but there's also a certain baseline of durability necessary to play professional sports. He may not have it.
He's been in the NHL for parts of 4 seasons now, has played 39 total regular season games but has been on the IR 4 times already (NHL only, not sure how many times he's been IR in the AHL, but based on his lack of workload down there, probably at least a couple). For all of the heat Robertson took for lacking the durability to absorb cheap shots, Woll has been way less durable than Robbie and without any illegal contact to explain the injuries.
and all of that is fine-ish. He still might build himself up to be durable enough to play 40+ games a season of average or better hockey, and I hope he does. But that's the type of shit you slot someone in as the 1B/Backup to figure out. You don't risk your season on it maybe happening.
