I don't think anyone is surprised that Shiffrin is dominating slalom. She is so far ahead of the field in that discipline that it is truly a surprise when she doesn't win by more than second. But she is also starting to dominate GS which maybe is not a surprise to some. Still if you look back 2-3 years ago she was maybe a top ten GS skier but rarely on the podium. Last year showed the first sign of a breakout when she won several GS races. This year it is starting to look like that if she is on her game in GS that she can't be beat. I think she is finally getting used to the speeds in GS and trusting her ability to arc at speed more and more (instead of the huge amount of stivoting we were regularly seeing out of her in the past). With this occurring she is becoming the Marcel Hisrcher on the women's side. I don't know if anyone will ever win 6 straight overall titles as he has but Shiffrin certainly appears poised to win several overall titles. And as far as win totals if this keeps up she will shatter Stenmark's record by the time she hits 30 (she is only 22 and has 39 wins). At some point in her career she will start to score regularly in the top 5 in SG and at that point assuming she still dominates Slalom and is always in contention in GS its going to be very hard for anyone to take the overall from her.
It continues to be so much fun to watch her progress. She was not a great GS skier several years ago. She keeps improving in each discipline.
I think I am wrong, after today's GS win in Kranska Gora she now has 40 career wins. Wow!!
