I just went on boxrec.com to get some idea of who Darchinyan's next opponent, Joseph Agbeco, was. He's from Ghana and he's the IBF bantamweight champ. Two things stood out about his record:
1.) Of his 27 opponents, 17 of them had NEVER WON A FIGHT. And 3 of his remaining 10 opponents had a combined total of 8 wins. To be fair, most of those fights took place in Africa and maybe they just didn't have records that were acceptable for boxrec.com - but several of those winless opponents were like 0-1-0 or 0-4-0. So who knows? But I don't think I've ever seen anything like that.
2.) Agbeco's last opponent, Luis Perez, does have a win over Dimitri Kirillov, who was Darchinyan's last opponent (Darchinyan won by 5th round ko).
I suppose that after Arce and Mijares, Darchinyan deserves an easy fight on Showtime - something to make him look spectacular. Maybe Showtime has a long term contract with Darchinyan (though I thought Showtime did all its business on a fight by fight basis).
