Yeah, both Celebrini and Michkov have shown enough in their play thus far to warrant the ranking, I think. Pretty rare for guys with those kinds of resumes to whiff. It happens, of course but not as much as you'd think. Frankly, I find Stutzle and Carlsson to be slightly more suspect on that tier. I wasn't impressed with Stutzle's 23-24 season ... especially his 18 goals in massively heavy usage. And while Carlsson is really slick, I'm not sold on him upping his production enough to be on that level right now. I'm waiting for consistent traction from him, as opposed to big flashes for a couple of shifts every game. For me, he's a candidate for the Marty Necas "obviously very skilled but still waiting for it to click" level.
I'm also thinking Nikishin is starting to be a bit under-rated. There's absolutely zero reason based on his play for his stock to be slipping and it wasn't long ago that he was widely considered a lock to be an impact first pairing guy right out of the box. Sometimes it's just a matter of boredom/impatience for list makers and several Russians have taken so long to get to the NHL that they slip a bit. Same thing happens to guys who stick in college a year too long. If Faber is a franchise player, so is he.
