Why does Arum need to use the Wilder/Fury fight to promote Crawford?

[QballLobo]

So they are holding the first Crawford/Porter press conference in the media center set up for Fury/Wilder 3.
If you needed a reminder how little interest Bob Arum has in promoting Crawford here it is.
A top P4P guy can’t even get his own press conference for the biggest fight of his career. Sad.

It's a brilliant idea doe. All promoters should do it.
It also helps the Fury/Wilder 3 attract more flies.
