Frank Corrado didn't just appear by chance; his arrival in Toronto was part of a whole series of events that all started when Vancouver chose a defenceman in the 2012 draft. The effects of that one event affected more players than just Corrado, and it hasn't stopped yet.
If the Canucks draft a defenceman, does that make an American move to Russia? Yes, is the answer. The Canucks, the butterfly in this story, drafted Ben Hutton and the effects rippled out in all directions. One of those ripples sent a man to Russia. Some of the ripples flowed in and out of Toronto, like a tide washing up defencemen and dragging others away.
