America have zero chance of winning a relay medal.
Diggins should be more like Alex Harvery and focus on herself.
My advice would be to drop the sprint and the relay.
I would 100% hope she drops the sprint, the first week is packed and its arguably going to be her worst event; she should be laser focused on the 10K imho. Of course Diggins being Diggins and the US team coaches being the US Team coaches, my guess is she will be skiing everything, stupidly. Hope I'm wrong.
There is no universe in which she is not going to ski the relay but I actually think it's good if she skis it. It's on the 14th, then Team Sprint on the 18th, then 50k on the 22nd. Plenty of time in between all those; for sure some could argue that skipping the relay lets her focus and relax more but that isn't going to happen anyway so the point is moot.
As always, much depends on skis and how the races unfold; she will have a chance in the skiathlon if the classic leg isn't skied hard but I don't see that happening. I think the Swedes are going to hammer the classic. The 10k is clearly her best shot at a Gold, obviously. No chance in the relay. For the Team Sprint I think on a good day with good skis Kern won't be too bad; no chance to beat the Swedes but I would not rule them out of a medal. 50k, even though her classic skiing has improved dramatically I can't see her beating Ebba and Frida who essentially have built the last two months of their seasons around that race.
