They'll tune in BUT this could be the biggest fight ever if more knew who Wilder was. His profile isn't that high in the UK, makes perfect sense to raise it since this is this biggest fight out there.
Assuming that's even remotely true, he could do that without having to go through a snoozefest like Whyte. I hope Wilder 'does' fight in the UK. Hopefully they could get in touch with Frank Warren and see if anything happens. But as Lou and others have pointed out, there is no reason to travel to the UK and fight Whyte to get to AJ just cuz Eddie Hearn said so.
TBH, a double header with Wilder and a Warren fight on the co-main could work nicely. Wouldn't mind if it was a Breazeale fight there either.
