Bullied
And you saying like Bergevin tells me you were either not paying attention or just echoing many people's dislike of him. Because if there is one aspect that Bergevin excelled in, it was trades. So "bullied like the last GM" is as inaccurate as it gets.
You also talk as if the Habs settled for the 1st round pick. Sure LeBrun said they would have preferred Pelletier over the pick. But Pelletier was off the table. And Habs were happy to get the pick, as well.
Sure you could have waited closer to the TDL to move him. But you don't know if you will get a better return then. For all we know, his value could decrease by then or even worse, he can get hurt. And with the way this year has gone for the Habs, that is a distinct possibility. Toffoli already missed time to an injury this year.
Position of strength.... one of the strengths of this deal wasn't just the return, it was also no salary retained. The Habs save 2.5M this year and TT's entire 4.25M cap hit over the next two years.
I'll finish with your comment that teams would have lined up. Habs didn't make Toffoli available. So it's not like teams would have been lining up. Habs would have gladly kept TT. This is a case of Calgary really wanting him.
