As of my last knowledge update in January 2022, Brandon Staley was the head coach of the Los Angeles Chargers. However, I don't have real-time information, so I'm not aware of any specific events or outcomes that occurred after that date, including any potential bust in Vegas.

If there have been developments or events related to Brandon Staley in Las Vegas or elsewhere since then, I recommend checking the latest sports news or official team announcements for the most up-to-date information. Sports situations can change rapidly, and my information might be outdated.
