I wholeheartedly disagree with you. Gary Bettman is the only reason we have an NHL club. Without his direct efforts, we would’ve witnessed the birth of the Houston Oilers, and that is recorded fact. The salary cap and revenue sharing helps small market US teams, but the fact is that at times when we have a $0.68 dollar and times aren’t good, we ARE a small market team. Maybe you are too young to recall when teams like St.Louis, LA, Colorado, NY, Detroit could simply outbid us. The current system is based on economic and therefore competitive parity. Some areas, such as Florida and Texas do have tax advantages, but those are relatively minor.
Levelling the playing field let’s Edmonton compete based on competence, drafting, developing, shrewd trading, and prudent contract offers. The cold hard facts are that successive management groups have been utter failures at these things. Bettman didn’t force us to draft Steve Kelly over Shane Doan. He didn’t force us to trade Taylor Hall for Adam Larsson. He didn’t force us to trade Jeff Petry for a 2nd. He didn’t force us to sign Nikita Nikitin, and Milan Lucic. We do have some legit disadvantages, namely a harsh climate and a rough travel schedule, but those are a piffle compared to garbage management.
The Vegas Golden Knights won by excellent scouting, a brilliant expansion draft, shrewd trades, and installing an excellent system of management. Ironically, I can see them falling apart a bit in the next few years because they’ve done some short sighted deals and bad signings under a “win now” philosophy.
TL/DR - The league is not stacked against the Oilers and Canada in general.
