I think this is a ridiculous take.
PD did not make all bad trades... he built a team that all the media and most fans fawned over. Some fans cannot see that Ottawa was not on many top players list of teams, and this made the rebuild difficult. This core is good. It can get better. As I said before, we needed another Giroux, but getting that leadership is just not available for this market. (Alfie can fill in a little, but we need that character on the ice).
EM has been gone for eons. Get over it.
DJ helped a lot of the players get moving. Why things have regressed, is a good question. I think, like many do, that DJ couldn't get them to the next level. That's fine. They should have let him go before the season, though because of the delayed ownership change, this didn't happen.
