This is a legitimately insane thing to say. Gudbranson is a perfectly fine 3RD who can play up in the lineup in a pinch, but if you have to make that pinch you're a dreadful team. Did you perhaps confuse Erik Gudbranson, career third pair, with Zach Werenski, actual top-20 defenseman in the league?
You're not wrong that a team would probably prefer Gudbranson to Liljegren, but it's not because Guddy is "better." He's tougher.
No. What? Who said that? I want receipts. No one said that. Peeke and Gudbranson are essentially the same player, Peeke is just younger and doesn't have the baggage of having been a top-10 pick or lengthy career of mostly sucking. And I say this as someone whose tagline on this website is literally "Gudbranson apologist."
Gudbranson is also likely out for the season with a major shoulder injury, so this is all moot.
