Add it all up, and the deck appears stacked against Williams. But Harbaugh spoke positively of the 23-year-old Thursday, indicating he wasn't afraid to put him in the same position in the future.
Of course, this what you expect to hear from the head coach. Harbaugh might prefer a swan dive off the Golden Gate Bridge before asking Williams to field a punt in another pressurized situation, but that doesn't mean he's going to share that with us, or Williams himself.
Williams said on Thursday he's trying not to think about where he fits on the roster. But that's probably just hard as blocking out what happened on that fateful day in January.
