I understand the perspective, but that positive variance is also what contributes so much to Shaw's value in the trade market. The PCA comparison is valid to an extent, but I don't think Shaw's skillset is comparable if you're doing an apples to apples comparison. I'm not saying Shaw is bad, far, far from it, but I also don't think he's untouchable.
I am also saying that he's at a position with 2-3 high quality FAs and he'd likely be the first ask in any potential trade deal for someone like, say, MacKenzie Gore, whereas I don't think you'd find similar interest or value with Caissie, Alcantara, or Ballesteros.
