Because they were underhanded. They tried to circumvent league rules. Seems you understand why, so why should it bother you? You think it was not underhanded but on the up and up?
I think it highly inaccurate to say they were underhanded. In fact, the judge hearing the Canucks' lawsuit against the league found specifically that "The Canucks, the Kings (and their representatives) and Mr. Patrick Quinn acted throughout with honest intention and forthrightness, Mr. Frank Griffiths, Sr., governor of the Vancouver Canucks, discussed the question of improving his club with Mr. Ziegler on more than one occasion prior to 1986 and learned from Mr. Ziegler that it was permissible to approach personnel of other club members provided no notice of employment was on file in the head office of the league in Montreal."
CanLII - 1987 CanLII 2461 (BC SC)
paragraph 14
Note that the Kings had not filed Quinn's contract with the league.
Ziegler found the conduct dishonourable and prejudicial to the league on the basis of having Quinn coaching one team while under future contract to (and having received a signing bonus from) another team. Fair enough. But Frank Griffiths had been told by Ziegler he could deal with employees of other teams unless there was a contract on file with the league (which there was not) and on first approaching Quinn's representatives was told to wait until after October 9, 1986 (the deadline for the King to exercise an option with respect to Quinn's employment after the 1986-87 season.)
After that date Quinn's representatives told the Canucks Quinn was free to deal. The Canucks' own legal advice was that they could deal with Quinn. The Canucks and Quinn agreed that Quinn would reveal his Canucks' contract to the Kings, which he did.
Now you may conclude their conduct was underhanded, but that word would seem to me to require some element of hiding things or dishonesty. In fact there was no attempt to hide the facts, Griffiths was at least to some extent acting on what Ziegler had told him and legal counsel for both Quinn and the Canucks were of the opinion that Quinn was free to deal with the Canucks.
In those circumstances I think it highly misleading to refer to "something underhanded" instead of giving the facts and letting the reader come to his own conclusion.
I think Ziegler had reason to find the conduct prejudicial to the league. I think the Canucks and Quinn should have considered the effect on the competitive nature of the game and the optics of having the future president of the Canucks coaching a rival. But I don't think the Canucks and Quinn were underhanded or dishonest.
If you're a real estate salesman and accept a job offer to sell cars starting October 1, you give notice to your employer as legally required and continue in your job selling real estate until the end of September. If you are a real estate salesman and accept a job offer to sell real estate in the same area with another company starting October 1, you give your notice and your employer probably orders you to immediately clean out your desk, watches while you do so and escorts you off the premises-even if you've been honest and above-board and even though you're legally entitled to accept a job with a different company.
What is gained by saying they did something underhanded instead of saying what they did? Did you not know, or were you just trying to be vague and mysterious?
