Definitely not ready to trade Power at this point.
however, I also know that McLeod is a 3rd line center and Krebs at best is a 4th line center.
That leaves Östlund and Kulich as your top 2 centers (though I doubt they through Östlund to the wolves right away)
This is my long winded way of saying that they need a top 6 center and need to explore every possibility, including trading Power
Just talking out loud here but if Vancouver is seriously considering an EP buyout after this season, maybe you need to explore what it would take to get him on the cheap?
