Why rant?Ok fine, but if you're gonna rant about boxing just go to that sub forum.
Manager does have KBer and he ofc should look good and watchable, preferably cool guy but will he have 4-1 or 5-0 record will not impact so much his career if he had lost nice fight where he looked good just on cards.
To have boxer with 4-0 or even 3-0 sadly is not rare cases better than boxer with 5-1-0 pro record and this is real life why boxing is with careful mathcmaking.
While for MMA or KB managers ofc are concerned that guy will not get damaged they are less stressed about lad's pro fight record 0 than in pro boxing.
