Deja vu all over again When Logan Couture left the Sharks’ loss to the Canucks after a high hit in the third period, the feeling was all too familiar. Vancouver was, after all, where they lost Joe Thornton to a horrific knee injury last season. It was deja vu all over again on multiple fronts, serving as a reminder of Couture’s own injury last season, when he missed the final seven games of the regular season after taking a ricocheted puck to the mouth. The nature of Couture’s injury is unknown, but the question now is the same as it was then: How will the Sharks make up for his absence? Fortunately for San Jose, timing is on their side unlike last season. Play Danny O’Regan For the immediate future, this is the most likely option. The Sharks waived Ryan Carpenter, at least in part, to give the second-year center an extended look. O’Regan’s assisted at a decent clip (four in eight games), and will likely play with the most talented linemates he has all year. But, he’s appeared somewhat overmatched in limited minutes, and just plugging him into the lineup still leaves the Sharks without a true center on the fourth line, as long as Barclay Goodrow’s out of the lineup.
