Daleman is the reigning World Bronze medalist and a better skater than Bradie. There is no way the judges at the Olympics would have put Bradie ahead when Daleman skated so well. Bradie lost to both Japanese ladies at Skate America, the exact point total is not really worth talking about, it's separate competitions and there has been a consistent clear message that Bradie is considered inferior. Satoko was given TWO underrotation calls in the SP at Olympics and still beat Bradie!
Mirai went out there and gave a HISTORIC performance that was better than what Bradie was capable of. Whatever the points were going to be, Mirai deserved more and deserved to beat Daleman, whereas Bradie would not have deserved to. This was always the correct assignment to make, in order for the USA to have the highest medal chance possible. Unfortunately the USA did not care about the highest medal chance, instead they went with what would give a Bronze medal while "preserving" Nathan Chen, which is such a stupid thing to do when he had the opportunity to make history with Silver + Gold medals (or even Gold + Gold, but he gave away the possibility of Team Gold with his SP performance). Like, is he an athlete or not? 4 performances over the timespan of more than a week is not that demanding and he wouldn't have even needed to do that difficult of a layout in order to win the Team LP.
