Is he worth it for just one season in a keeper league?

Given how he has acted this year, I assume he will leave the NHL once his contract is over this summer.

If he comes back for 75% of the season will he be a fantasy impact defencemen? I am thinking of a league where the best free agent d-men are guys like Stralman, Colaiacovo, Yannik Weber, Kurtis Foster, etc.
