This is hyperbole, no?
You think all-star level forwards are much, much easier to find than defensemen who haven't played an NHL game yet? That's a unique take to say the least. Fiala is a top 30 NHL scorer, teams are lucky to have one player of that caliber. If they aren't difficult to acquire, why doesn't every team have 2 or 3 guys at a ppg?
Top-4 defenders don't play 25+ minutes, that would be a true #1 there are only maybe 10 guys in the league that do that. I like Faber's game, but if he turns out even close to that I'll be completely shocked. I always saw his ceiling as a 2nd pairing defenseman, and a good one at that.
He's maybe in the top 25 of prospects, and that's being favorable. I put him more like top-30, which is still fantastic. But you are talking about him like he's the next coming. I understand you are high on Faber, but come on...
Also, the reason the Kings don't have a 25+ minute shutdown guy is those players don't exist - they ALL have some level of offense. You don't play them that much otherwise. And the Kings already do have a young shutdown guy who can handle anyone, that's Mikey Anderson. Ask McDavid about him after he was up in his grill the entire last game.
Whether Faber wanted to sign or not, you make that trade 10 out of 10 times.
