If Fury was outboxing Wilder and Wilder landed one big punch and ended it then yeah give Fury the chance in a third fight to get the win
If Fury outboxed Wilder for 12 rounds and got the win they yeah give Wilder the chance in a third fight to land that big right hand and get the win

Fury comprehensively beat Wilder, not only outboxed him but outpunched and stopped him as well, the questions have been answered for the fans, no need to do it again, if they have a 3rd they may as well have a 4th and 5th
