Couture is no worse than most I recall carrying the C, only with far less meritable a squad for current evaluation.
We were spoiled with Pavs who I consider our best captain (only going by the Sharks era i've watched, which was back when we had another Sturm breaking his legs on a non-auto icing).
I think Couture will lead us as far as his trade, which I suspect will be akin to a Burns return rather than a Meier one if he wants that Cup 'cos it's not coming to the Tank in his career short of the flukiest fluke of all flukedom.
I disliked the negative, kinda torn-faced approach he adopted, tho' obv just his nature, but he was the obv go to after Pavs departure, I'd give Hertl the mantle post-39
Edited to add: Mumble mumble, something about a future draft, send someone up the rigging we have a celebrini to hoist, continues mumbling OT...
