Why not have a trilogy though? If the money is there in the table, they why not?
Usually a triology is interesting when two fighters are one and one in the win column and to know the ultimate winner a third fight is scheduled and if Andy Ruiz wins the second fight then what interest does it have from the audience when they know the result.
If Joshua wins then if will be 1-1 and a final fight is needed to happen in order to settle everything. Just a matter of days now, and I'm sure boxing fans are eagerly awaiting and excited to watch this fight.
Everyone is waiting to see what happens in this fight as Anthony Joshua needs to win this fight to have a successful career in boxing and a loss here will halt his career.
