Yeo and Green weren't even in Vancouver at the same time, so I'm not sure why or how he plucked Yeo out of Vancouver. Baumgartner is his guy from when they were in Vancouver (I think they were both fired together?) but Yeo was an assistant in Philly, who was getting ready to soon become the interim coach after AV was fired. Or maybe AV was fired by the Flyers before Green/Baumgartner were fired by Vancouver. They were both fired right around the same time.
Yeo didn't come to Vancouver until the next season.
I'm guessing this is all coincidental, but I've seen people (incorrectly) talk about these connections as if Yeo was one of his guys from Vancouver. He was not. They did not intersect there at all. Now maybe they've worked together somewhere in the very distant past, but it was never in Vancouver.
