I think Kovalev has more heart then Koivu, at least outside the ice, but I am biased.
Kovalev is the one responsible for converting me from a Avs/Nords fan to a Hab fan.
I don't now why, I just don't like Koivu at all.
Yeah more heart than Koivu off the ice. Koivu only started a foundation to get an MRI machine worth millions for the Montreal hospital. He received an award from the NHL for his humanitarian work as well. I like Kovalev but if he had half the heart of Koivu he would be an all-star every year.
