Strength in the jumping abilities of the girl is definitely a key asset, so we will see. I cannot imagine that it was always straight forward and easy though, for him to be part of a team where the coach was the girl's father. In that situation, the priorities must have always been a bit of a paradox for Josh, with Ashley skating both singles and pairs. When she went off for her Junior Grand Prixs, he was left to train by himself. Not an optimal way to prepare for Senior Grand Prix events in pairs, and if you are him, you are wondering whether the compromises are not sufficiently aligned to your goals.
Good luck to them both. Need more strong pairs and if it took cleaving and re pairings, that seems the nature of the sport in the US unfortunately.
