All of those guys play about a 1:30 mins a game more than Bear.
I don't know what Bear is worth in Arb, but if you are using mins/game he is definitely not on their level.
I know it does depend on what age a contract is signed for as well, not sure who of those guys matches there.
I don't know Arb well enough at all to say where he should end up.
walman is 27, cernak is 26, anderson is 23, siegenthaler is 24, ristolainen is 28
if you don't like those comparables there's also zub (26, 4.6m, less minutes and points than bear), fabbro (24, 2.5m, less minutes and points than bear), samuelsson (23, ~4.3m, more minutes but less points than bear), nic hague (23, ~2.2m, less minutes and points than bear), jacob middleton (26, 2.45m, more minutes but less points than bear)
all those deals were signed post trade deadline 2022 so they're all recent
the only "good" comparables for bear from a canucks perspective are middleton and hague and neither have nearly the nhl track record bear has. middleton only had a single nhl season under his belt and hague was a 6th/7th dman when he signed his contract
apparently dhaliwall reported today bear is looking for high 3s for anything other than a one year deal. i think that's right in line with what he can expect in arb
