I heard from a reliable source that dad asked Nike for 1.2 million and her own shoe. Since Nike has the right to refuse option in her NIL, they said, no thank you, we will wait to see what you get from our competitors.
In addition, the trials and Olympics then exposed her. She can't close with the best in the world over 5k and 10k. She might in the marathon however it is remains to be seen if she is durable enough.
