It's called salary retention, he retained a percentage of his remaining contract, you can't just buy out the remainder of the contract in the process of trading him. We will pay a specified portion of the salary that is owed to Schultz and the Pens will pay the other portion and get a reduced cap-hit as a result.
Completely agree we need more experienced players, but now is the time of year when experienced players generally cost the most (aside from players on horrible contracts). Best to go vet shopping at the draft when picks are at their most valuable, or through free agency when experienced players don't require the expenditure of any asset other than money. This season is down the tubes no reason to pay full price on something that you know will be cheaper later.
I'll go half and half with you here, signing Schultz to any extension at his RFA qualifier or beyond was a mistake and I called it out as such in the offseason, we also gave him way more rope and icetime then he deserved and should of limited his minutes or benched him completely for long stretches of the season after it became evident he was a huge liability, all his gaffes and the losing he contributed to wasn't worth a 3rd round pick. I give Chia a small concession in that he was new to the organization and not fully familiar with the player (though I think sitting down and watching a couple hour of clips would of been enough to decide not to sign him), I suspect he relied on his assistant GM's opinion on whether or not to sign him and the wrong decision was made. If he makes a similar mistake in the future now that he is familiar with the organization, its players, and the people who are feeding him their opinions I won't be so lenient.
With respect to Purcell I can't really call him out on that, its a player already under contract with the organization and in an ideal world I'm thinking they want Ebs and Yak as the top 2 RW's on the team, but between injuries and Yak just not playing upto that level Purcell took on that open spot. Purcell was little more than insurance against Yak not being able to hold that top 6 role and while he's a player there was no future in, he still filled a hole that needed filling. While placeholders might seem stupid, if there is a player you think can grow into that role, but just needs a little extra time to get there it's not an inherently bad idea to have someone in that spot or who can atleast challenge them to fight for a certain spot in the line-up and seize it from them.
It didn't sound like he was done to me, it sounds like he has more irons in the fire, but I'm not expecting a big splash and I don't think now is the time for a big splash either. If we are to trade a young gun the best return will likely be at the draft and there will be more teams that can get into the discussion with more salary cap space available to play around with. Good teams also hold onto good players pretty tight, but an embarrassing playoff performance can at times free those players up that wouldn't normally be made available at any other time in the year.
