Friday is something to do with the College Football Hall of Fame.
So they stopped by to pay homage to the legend before his induction? Makes sense.
Leavitt going to San Antonio makes sense. I'm pretty sure he's out of a job, so maybe he called Bill, Bill told him to come to SA, maybe they had a nice conversation, a potential opening for DC came up, etc.
If Venables is in Manhattan, well, that's weird. Maybe he had a delayed Christmas celebration with his family or something due to bowl season and just decided to stop by.
