Schrodinger’s Cat is one of quantum mechanics's most famous thought experiments. In the experiment, a cat is placed in a box with a vial of poison that will break open at a random time. Since no one knows when or if the poison will be released, the cat can be thought of as both alive and dead until the box is opened. The same applies to Trey Lance this preseason.
Simply put, any time a player steps out onto the football field, they assume risk. We saw that with Ryan Jensen today, and we saw it with Trey Lance last year.
