I guess there's a minor chance to drop Svahn, but likely not in a decisive way. The battle for 3rd will probably be more interesting, with neither Germany nor Finland looking great so far. Let alone USA.
I don't think anyone of those first leg skiers is dropping Svahn; she has shown in the past when on form she is a very sold distance skier and 7.5k is not far. And she really showed some in the sprint, those were some long, very tough rounds leading to the sprint final, and then making the likes of Sundling look mortal, frankly I won't be at all surprised to see Svahn detonate this race on the opening leg rather than struggle to not get dropped.
What a team for Sweden; you have Ribom, Ilar, Dahlqvist, and Hagström on the sidelines, that is arguably a medal winning team right there. Wow.
Norway has a really solid team but they simply are not going to touch Sweden; that said chances are good no one else will touch them either, Slind and Weng be good, maybe if Fosnaes or Simpsen-Larsen has a really off day.
The Germans will likely have good skis and if all of them ski their A-game they're clearly a solid threat for Bronze; I also see Finland in with a shout for Bronze too; again, so much of the fight for the last medal will come down to who has the skis and which team can avoid having that one skier who just melts down on the day. Also agree with BullsFan, Switzerland is for me a dark horse for a medal, they have been getting some sneaky good results and if they medaled that would be the highlight of the competition so far for me. (Along with Estonia cracking the top 10!

)
Sad to see Finland without Parmakoski; her results don't merit inclusion on the squad but still, she was always a favorite of mine, end of an era.
And then the US. Holy. Crap. If this team gets near a medal I will believe hell has frozen over. Honestly, I'd love to be wrong, but wow. Only Kern is the right pick in the right leg, period. I don't know in what universe you select Brennan for this; she's done NOTHING to warrant a relay spot. Maybe for the coaches it's "Here's your (not very realistic) chance to finally win a medal Rosie", or maybe a lifetime service award or maybe are hoping for a miraculous return to something like her former self but after finishing over 6 minutes down in the skiathlon I can't fathom her finding the form to do anything but set the squad back. The only thing she has going for her is she didn't ski the sprint or 10k so might be relatively fresh. As inconsequential as Swirbul has been she would still be a better choice imho, Rosie is just so far off right now.
And putting Diggins on anchor, what in the actual hell? I originally thought she should be 1st skate leg but with this lineup 2nd classic leg would be so much better. I can hear Chad Salmela and Kikkan Randall now, "If anyone has the pain tolerance to close 3:30 in 7.5 kilometers to Jonna Sundling it's Jessie Diggins!". What a disaster; I would dearly love to be proven wrong here but I will honestly not be at all surprised if they are 7th or even 8th.
