As to betting, that is always depending on what we think and on how this find will end up, of course with the fighter of your choice.
I'm maybe wrong but Terrence Crawford is not yet a big star in boxing these days that may be the reason why Top Rank decided to make the PPV price a little bit cheaper to attract hardcore boxing fans to buy. The target market for this PPV will be the US and I don't it will reach 500K buys as Crawford is not yet a draw, hope Bob will realize that and let Terrence fight whom he feels could bring him to stardom.
This Porter fight maybe the start, hope if he wins this one he will fight Thurman next.
You want stardom for Terence Crawford, however, you want him to fight only against Keith Thurman after building his name from a victory versus Porter hehehe. The next fight should certainly be versus Errol Spence. Crawford and Spence are the kings of boxing’s welterweight division.
