Deadline returns have always just been weird like that. It's almost like there's a saturation effect on prices - the stars don't go for that much more than average top 6 players, who themselves don't go for much more than bottom 6 utility players. I don't know enough about microeconomics to put a proper label on it. I'd guess it's a balance of risk - i.e. most teams don't win the cup - and needing to look competent. There's only so much GMs are willing to give up for a rental when it's likely they'll still lose. On the other hand, contenders are expected to at least pick up someone, so the price of depth players is inflated.One thing that I hope has already been pointed out is how incredibly weak the returns for Kovalchuk and Hossa were. Bergfors and Armstrong, among other issues, went straight downhill. That's not to say the Stone returns should or will be as weak. It could be that teams were just seriously underbidding when elite level talent was available, offering more or less similar packages regardless of whether Hossa (higher tier) or Ladd (lower tier) were on offer. I'm curious to find out if that market imbalance is corrected this year.
Hossa went for not much more than Ladd, who went for not much more than Gaustad. There's variability year to year, but prices have never come close to some of the returns Sens fans have been suggesting.
I wouldn't hold out hope that one of the most incompetent teams in the league right now will be the one to change that though.
