Wennberg is a good example.
He was bought out of his contract @ 4.9 aav, but for fewer seasons - his buyout was 6 years, not 9 years.
An owner can say that about any buyout. We have seen owners make early decisions on buying out players due to timing reasons - Parise, Suter, OEL and others have even done so because a GM had a strong preference to jettison the player and the contract even if that player was still very productive, ala Duchene.
KK turns 24 this summer, so they could give him one more season before they maximize the 1/3 buyout rule for players under 26.
However, if they need to pay their RFAs (Jarvis, Necas, Drury), resign or replace Pesce and Skjei, and resign Guentzel, then KK could be bought out.
