If Jade is 2nd in the combined Nationals + Trials AA results, then she is automatically on the 4-person team. And USA will have to forfeit the individual spot, so only 5 USA women will go to Tokyo.
If Jade is 3rd or 4th in the combined AA results, it'd be up to the selection committee to decide if it's worth it to forfeit that 6th Olympic spot so that Jade can be on the team. It's not like USA is in danger of losing Team Gold without Jade's scores.
Based on what I saw yesterday, bars appears to be their weakest event, and beam is 2nd weakest. I think it'd be wise to select someone strong on UB/BB in the 3rd and 4th team spots. Suni Lee would fit perfectly, but she fell on both yesterday. Morgan is another possibility, but she's injured and didn't even do bars. LeAnne Wong had strong beam, but fell on bars. Riley McCusker is excellent on UB/BB, but she's injured. Argh...ALL of my 4 favorite American gymnasts had terrible days yesterday!
