Maybe you've heard of him?
As an awesome article published earlier today by The Ringer explains:
Rice is the NFL’s all-time leader in receptions, receiving yards, and touchdowns. Many would say that the former San Francisco 49er and Oakland Raider is the greatest player to ever put on football pads and a helmet. He also happens to be a hall-of-fame wedding crasher.
Yes, according to a quick Twitter search. LOTS of references to Jerry Rice crashing weddings, going back years.
Sounds like such a cool post-career hobby!
