What I saw was a degeneration of Shiffrin's technique and boot set up. She skied sloppy and undisciplined. The US Team coach was asked what he would tell Shiffrin for the second run. He responded, "Nothing". Well, I have news for you. A racer who should be winning in this field by 1 second, at the least, and is .04 seconds out, needs some advice. She is skiing the new boot and it's not close to being correct. She is loading everything under and below the gate, she is unweighted too long between arcs.
She needs a technical coach and her mother isn't up to it. There will be frustration in the Shiffrin camp and they won't know how to fix it.
