You really need to reevaluate what injury-prone means. Just because a player has had an injury in their career doesn't make them injury-prone. You call to have the players on this site untradable and injury-prone because previously they had one injury.
That being said tearing apart what works to make something that doesn't completely suck is futile. They aren't destroying the Left to fix the right. That makes no sense.
Muzzin by nature is a shot blocking, physical defenceman, and he isn't getting any younger. Players like that get injured, especially with age. He won't probably play a full season for us, so leaving him as the one capable defenceman on our left side is silly.
Also, they are destroying the left to fix the right. Reilly is literally our best defenceman, by a mile and a half. He was the top offensive defenceman in the league when he was healthy 2 years ago, he drives our offence and not only that, he's on a great deal for 2 more years. Trading him so you can move in a teenager who probably needs more time in the AHL and a KHL guy who's never been to North America is risky as heck. Add in Muzzin missing 15-20 games with injury from blocking shots, hitting, fighting, etc. and our left side would be KHL guy, Sandin (20 years old, 28 GP), and Marincin or Rosen.
Our right side isn't even that good either, an overpaid Adam Larsson is an offensive black hole, nothing more than a shutdown guy who is terrible at puck-handling, and he's only got 1 year left on his deal. Hamonic is 'good', but nowhere remotely in the same dimension as Reilly, and looking at his analytics he was horrible defensively this year. Then there's liljegren, who has shown no evidence he's remotely ready to play in the NHL, let alone be an impact player. We'd be butchering our prospect's development, moving out our underpaid stud franchise defenceman to bring in an overpaid mediocre shut down guy, and a guy who is spotty defensively that hasn't played a full season since 2013.
