I'd take this with a pinch of salt as it's come from Nelson, but if this comes off then this could be a great fight.
The only downsides are not so much about the fight itself but for the fighters. Should Bakole lose, it would make his record look a bit suspect considering he's a decent boxer but has lost to two guys who's records themselves don't reflect their actual skill level, he would need quite a few more fights to get himself to a world level position. On the other hand, i'm not sure Bakole is the "big name" opponent that Hrgovic needs to get some recognition from casuals to allow him to get some better fights and paychecks. But again, the fight itself should be great if it comes together.
