Depends on how you look at it. In terms of the roster on the ice, no. Perron for Brouwer is a wash(or possibly a slight gain), but Sobotka for Backes is a severe drop. Allen in for Elliott makes me mad, but Allen has shown he's capable of being a very good goalie, so it's either a wash or a slight drop.
However, had we signed Backes to 5x6 or Brouwer to 4.5x4 we would be in a worse position as a franchise IMO. The team on the ice for next season would be better, but those contracts would've really limited what we do in the future.
I'm not happy Backes is gone, but I'm happy we don't have to pay him 6M for the next 5 seasons. And that Brouwer contract is god-awful.
