If Crawford called out Floyd?

[Ron Swanson]

He'll be fighting Horn for the Top Rank belt.

If horn beat Pacquiao convincingly in a rematch, Crawford would destroy Horn. Although, I think that for Crawfords sake, beating Pacquiao would boost his status much more.

Well surely. But if Pacquiao wanted that sort of action we never would have seen Pac/Horn. Pac is retired, whether he fights on or not. Same as Floyd. They aren't top guys anymore and aren't interested in top guys.
