What are you talking about? It's grade 2 math if you can't understand simple, and I mean simple math, no one can help you. You had a pick an prospect added a NHLer lost an NHLer ... -1-1+1-1 ... pretty simple.
A day before the draft our roster had all of our players (including Kerfoot, Hill, Dermott, Engvall all of whom would be exposed in the ED). We also had all of our prospects (including some B levels like Hallinder) and we had limited draft picks, but we did have our 7th.
...after the ED we still have all of those pieces with the exception of Hallinder and the 7th...because that is all we lost. It cost us those two assets to keep our roster in tact...think of it like we traded Hallinder and a 7th to Seattle for them not to take Kerfoot (or Dermott).
I don't see how people are seeing this as us having lost McCann AND the assets is cost us to acquire McCann.
...if I have a dollar and exchange it for 4 quarters and then someone takes my four quarters I am down only a dollar, right?
