Context: In the manga リクドウ, Riku is going to fight against Hyodo. Hyodo is a boxer and the son of a former world champion boxer, so he's a thoroughbred (サラブレッド). He didn't have a good relationship with his father so he moved to Yoneda Boxing Gym. Yoneda is a trainer that has recently inherited his father's boxing gym. The two seem to make a good team together. Hearing about all this, Riku's trainer says:
What is the meaning of ボクシング親子同士のペア? To me it translates to "a boxing couple with a father-and-son-like relationship", but the fact that they seem to be about the same age made me think that my translation could be wrong. Could it refer to the fact that they both continued the profession of their fathers and so, in a certain sense, they are both thoroughbred?
