So as backstory, someone asked Dave on Twitter if he felt ROH could draw 10,000 for a show. Dave replied probably not, and Cody Rhodes saw that and took as a challenge. He and the Young Bucks announced they plan to promote a show aimed to be the first non WWE show to have a crowd over 10,000 in the US since WCW died.
Clearly as over as the Bullet Club is, they can probably pop the largest non WWE crowd in a while...but 10,000 sounds like a pretty ambitious goal unless they were able to get New Japan to send some big names.
My other thought is I wonder if Cody and Daniel Bryan have something worked out. They've been working a program on Twitter for a while, Bryan clearly wants to return to wrestling, and if anything has a shot to draw a 10k crowd you'd think that would be one of the matches that would get in the ballpark.
