How Good Was the WHA: Major League Teams
We've seen that the calibre of the World Hockey Association's top stars was high enough to call the WHA major league hockey. But hockey is not a superstar game. J. C. Tremblay was a great player; him and five AHLers make a good AHL defense. Your team would get smoked by the worst team in the NHL in a seven-game series and nothing Tremblay could do would make much difference. How can we judge how good the actual teams, from Bobby Hull down to the worst fourth-line goon, actually were compared to the NHL?
Just on the off chance a young person is reading this, I'll tell you something old WHA fans know: the one way you must not answer this question is by looking at what the four WHA teams accepted into the NHL did there. The NHL-WHA merger is often called a "surrender," where the NHL teams ruthlessly pillaged the WHA of their talent. It was a bit better than that; the WHA teams were permitted to keep three to four players officially, and in practice kept many more as the NHL's hard line softened once it was official that they'd actually have to share a business with these guys. True, there was some lingering NHL spite: making the WHA teams pick last in the Entry Draft rather than first, and denying Wayne Gretzky the Calder trophy on the grounds that he already had major-league experience. This did not wind up hurting that much: of the four Hall-of-Famers selected in the first round in 1979, two went to WHA teams (Michel Goulet to the Nords and Kevin Lowe to the Oilers), and Gretzky's legacy is fairly safe. They lost most of their top stars, but not all of them, and the NHL honoured Gretzky's personal services contract with Peter Pocklington rather than fight it. They were more like "expansion teams plus" than true expansion teams. Only the Quebec Nordiques finished last in their division their first year in the NHL, and they weren't a bad last. However, what they weren't was representative of the teams as they played in the WHA.
Going through each player on each roster would be more noise than signal. If you can compare half-century-old third-liners across two different leagues statistically and come out with a comprehensible result you are a better man than I. In baseball you can look at a guy who hit .280 and the pitching he faced and say something; in hockey ice time matters and we don't know it. There isn't enough video for even objective comparisons, and who'd have the time to watch it if there was? What we want is a corpus of how WHA teams played against NHL teams, or teams that NHL teams can otherwise be compared to; very fortunately, we have it.
