My only argument for trading Hanifin is, you drafted him with the expectation of getting yourself a high-end first-pairing guy. Unexpectedly, you got that with Slavin, who is cheaper in the immediate future to boot. So in a way, you're playing with house money now.
Nor can I really fault JR for trading Pronger. I mean, he didn't get some washed-up piece of trash, he got freaking Brendan Shanahan. One of the very best PFs to ever play the game. And that asset eventually became Brind'Amour. Do we ever want to think about what this franchise would be without Rod Brind'Amour.
I'm not saying I'm all in for trading Hanifin 100% but I'm also not on board with this idea that he is completely untouchable. If it's for the right player....I mean, Duchene, Aho, Rask, Skinner, Staal, TT, McGinn, Nordstrom are a formidable forward group in the long-term and we still have 1-2-3 on defense as good as anybody else's in the league.
