A one year negotiated extension is not at all surprising , and fits well with the situation that both organization and player find themselves in. The contract amount is probably fair as well.
Got to give Copp some credit here - he's betting on himself and taking a significant risk that he can keep his level of play high this season, even though many suggest last season might have been a bit of an outlier (6 team canadian division only). If things do not unfold as he forsees, he could have much less success with his first UFA contract negotiation.
