If you're really un-doing trades you need to remove the following from the roster

JFK - part of the Hamilton deal who came via Kessel deal
Smith - part of the Seguin deal who came via Kessel deal
Hamilton - part of the Kessel deal
Carlo - part of the Boychuk deal
Chiller - part of the Lucic deal
Jones - part of the Lucic deal

You'd also lose the following prospects

Senyshyn - Part of the Hamiton deal via Kessel deal
Lauzon - Part of the Hamilton deal via Kessel deal
Zboril - Part of the Lucic deal
Kuraly - Part of the Jones deal via the Lucic deal
Lindgren - Part of the Boychuk deal

Some you noted, but most you didn't.

I love when people do this....

When everyone does this, they miss the point that all these players were developed into the players they are today. Also, hindsight is 20/20 who would of drafted Benn? Rakell? and a few others. You are basing this off what you know not and I know it is for fun but look at all the players everyone else passed up prior to this.

Not to mention that with a different roster means potential for a different finishing spot. That means that potentially you're draft earlier or later than you did and maybe based on the current line-up you don't draft the same guys. This doesn't factor in management changes either. What if the non-moves PC did (i.e. Kessel) meant he got fired 2-3 years earlier. His preference in players is difference than Sweeney's. Then you have the coach as well, without those moves Boston doesn't win a cup in 2011 and suddenly CJ isn't put on a pedestal anymore and maybe he gets fired 2-3 years sooner. It's a rabbit hole people head down when they do this lol.

Also you are 52 million over the cap

Exactly!

Hindsight 20/20 you think man we could of ended up with all this but we traded that pick and this pick and blah blah blah. Just have to look forward to the future of the team and not the past.
