@walsha It's an issue only when a player asks for a trade and uses said clause to direct where. The agreement clause relates to no move/trade. If player breaches, he can't then use the clause to manipulate the trade, but you'd be the first calling that unfair, so it becomes an issue.
@DomUn1que Dallas gives up two near top-tier players, a depth D and a first to acquire a Norris-winning D. Verdict: they likely need more coming back.
The question becomes how much more would Dallas ask for from Habs?
@DomUn1que MTL - gives up 2nd best prospect, a 1st and a 2nd to acquire top line winger + depth D. Verdict - likely need to add.
CBJ - gives up TWO best players but add an excellent D, an NHL forward with high ceiling, an excellent prospect, 3 decent draft picks. Verdict - close to fair.
