I’d be surprised if they ended up splitting dance in the team event. Ladies and Pairs are where Team USA are the weakest, especially the Ladies. I don’t trust any one of those girls to successfully handle both the short and the long, so I’d want to split that one for sure. And we can’t assume that Nathan will be willing to carry the men’s portion on his own, so they might have to split that one.
In my opinion, the best strategy is to split the Ladies using Bell and Chen and split the Men‘s using Nathan and Jason. For Pair’s, I‘d let Cain-Gribble/Leduc do both portions. I’m not sure how well Frazier would hold up considering he’s still recovering from the *****. As for Dance, either H/D or C/B are capable of handling both portions and scoring well, so I wouldn’t split that one. The only problem for me with Dance is that I’m afraid C/B would get the nod over H/D as they are the national champions, and my preference is H/D.
