Written Option 2:

Oliver knew about the invitation before the regular season was over. Fox Sports-LA wanted him and a few of his teammates to come in and do some sort of commentary during the off-season. He accepted, since the money sounded good and it'd be a good opportunity to try out a possible retirement plan if he wanted to stay in the sporting world. He was figuring that maybe the call would be for lower level hockey leagues or possibly PBE or ISFL. But when the packet finally came the night before he was set to go to the studio, it was for... Indoor Handball.

What the actual fuck is Indoor Handball?

But, with 12 hours to spare, Oliver knuckled down and spent a few hours studying what he could with Wikipedia, international websites (it luckily has a pretty big following in France?), and YouTube videos. He still ended up winging it and asking for clarification of some things from the more knowledgeable play-by-play announcer, but it all worked out and the producers seemed happy with his work.
