Thank you.
You can't logically say he should have been trade bait and that him signing his QO was Nill's fault or a mistake. This is hardly anything noteworthy, and any team that may have traded for him, and about 95% of fans could predict that the second he was qualified, there was no way he wasn't signing that contract. If he went to arbitration, he could have lost money, up to 15%. The only two options for Janmark were become an UFA (team choice) or make $2.3 million next season (player choice), with Dallas or another team.
If you want to argue that they should have not qualified him, I disagree, but not enough to debate it. There is no debate that exists about qualifying him vs. trading him. If he had value to a team, that team knew he was either signing his QO or they were praying Dallas wouldn't qualify him. This forces their hand. If they want him, they have to trade for him.
