My dad and grandpa used to say they “would get big and turn colors” the more fat they ate. Seals, moose etc. the more fat, the darker the coat. It also had an indication of weight. No seals around colville but I bet there’s some moose. 
From what I see and hear, the moose numbers around Colville are significantly less than they were just a few short years ago unfortunately! Follow on packs will have to grow big on beef, because we can still grow that population. So frustrating!
I do hope we get to see this wolf at 200 pounds that is more than a bit to imagine. I am glad it is gone if its only 80 pounds.
