Is there anyone here who actually uses that argument? Seems like the kind of argument posted on Twitter by a bot account with a blue check than anything a real person would make. But I've also seen the posts people make about Atlanta, so I suppose it's not outside the realm of possibility.
No, the number of Habs fans in QC is no reason to avoid putting a team there. I'd love to see QC join the NHL with Houston, Atlanta, and Phoenix. However, looking at QC from an impartial business sense, the market is small, has limited corporate support, and there's no telling whether PKP is even interested anymore (and further, whether or not anyone else there has US$1bn burning a hole in their pocket).
I'd love nothing more than to see that blue sweater make a return. But there are hurdles to leap, and a BoG who will have to be convinced.
