Quoting: Windjammer
Dvorak = isn't needed or wanted. No value to Winnipeg.
Xhekaj = a low end LHD that isn't needed or wanted. No value to Winnipeg.
Trades don't worth that way. You just don't get to dump all the valueless pieces you have and no longer want on the other team. You'd have to give the Jets pieces they need or want or they just move on to the next offer.
So with two pieces that have no value to Winnipeg, it is less than Horvat got.
There's a difference between valueless and no value to Winnipeg. You didn't say wrong package, you said less value than Horvat.
The two pieces that matter, are Beck and the 1st, which is almost certainly more valuable than the 2 pieces for Horvat, and that's not specific to Winnipeg.
Beauvilier was a partial throw in for cap similarly to Tatar in the Pacioretty trade. You hope to get value from that player, but it's not a piece you are expecting much from. The value difference is negligible whether the player is desirable or not.
Xhekaj is not without value, but he's value above and beyond Horvat's package regardless of specific needs. Maybe you keep him, maybe you flip him, maybe you look at another piece to replace him in the deal.
There's room to negotiate, but dismissing half the package as "dumps" (which they aren't) when the first half is already superior, is an objectively bad valuation.
For the record, I don't even want Montreal to trade for PLD and certainly wouldn't offer those pieces. I'll acknowledge that it would take something like Beck and the 1st to put together a package, but if I were to make an offer centered on those 2, I wouldn't go higher than this. The other pieces can be swapped laterally in terms of value for a better fit, but that's not the part of the trade either team should be balking at.
