I can't see a single way it would make sense to trade Murphy for Dimitri Mironov. I also can't see how it made sense to give him away to Detroit. It was the trade deadline - make a contender pay you something for the guy. I remember being happy to just lose him and get younger as a team, but in retrospect, who does that anymore? Even a broken down Mark Streit was worth something at the deadline, and this was Larry Freaking Murphy.
IIRC, a major difference between the Streit situation and Murphy was that while Streit was an impending UFA rental, Murphy was in the middle of a backloaded deal the Leafs gave him after acquiring him that still had one year left at a higher salary. I'm guessing his cold reception in Toronto and his drop in production might have wrongly signaled to other teams that he was trending down and not worth taking on the rest of the contract.
Murphy also had a no trade clause at the time, so I'm sure that also hurt potential returns.
On top of that, the Red Wings didn't just get him for nothing... The deal also included the Leafs retaining 1/3 of Murphy's salary for 97-98.
But yea, it is pretty crazy that a dman on a 50pt pace couldn't garner some sort of measureable return for the Leafs. Then again, their fans and media didn't help his value at all by making their highest paid player the scapegoat for a bad season (and coaching).
There's a good post somewhere on the forum that summarizes Murphy's failed Leafs tenure. I think the gist was:
-After seeing him in the playoffs two years in a row, including a 1st round loss in the most recent year, Leafs fans were hoping for their own Chris Chelios. Instead, they got Murphy, who while similarly productive, was the complete opposite in terms of defensive style.
-Then Murphy has a less than stellar playoff series (0G, 2A, -8 in 6 games) in a 6 game loss to the Blues, where the Leafs allow 4 short handed goals.
-It's not a secret that Murph's main weakness was skating. However, he was very smart with positioning and adept at moving the puck out of his zone with well placed dumps up ice. That said, in Murphy's 2nd season in Toronto this seemed to be lost on 1st year coach Mike Murphy. Coach Murphy wanted the D to skate the puck out of the zone, which meant player Murphy (and the Leafs) would be in trouble if he needed to get back quickly if he somehow lost the puck. In front of a market that's probably the least forgiving of defensemen, that's an absolute recipe for disaster...
