The play-caller took charge of the team at the under-20 European Championship Women in Sofia, Bulgaria looking for a place in the top flight. And although promotion to Division A wasn't forthcoming, Buckle believes the experience proved priceless for not only the players themselves, but also for him, as he ponders who might be able to step up and push for a place with the senior side.
He explained, "Coaching both teams gave me the opportunity to look at the overall structure and make sure we can continue to link both programmes so they obviously have the same principles.
"The team have a number of talents including Cheridene (Green) who must now focus on making an impact at Junior College in the States.
"Janice Monakana had a good tournament and I also thought Harriet Ottewill-Soulsby was absolutely outstanding for us.
"The other bonus for me and I guess in some ways, something of a surprise, was Hannah Peacock from Scotland.
"She really made some strides during the competition."
Great Britain were involved in a string of tight games and just couldn't close out enough of them to gain a precious promotion place. Nevertheless, their ferocious competitiveness and some important learning outcomes mean it was a hugely valuable trip.
"We fought really hard and as best we could, since our preparation wasn't ideal," mused Buckle.
"I think the main thing that came out of the tournament, is that our young guards in particular have some things to learn.
"They did okay for us, but I think at that level, they maybe didn't look as experienced as they could be.
"It was good being able to work with them through the tournament and to be able to emphasise those things they need to be doing if they want to make the transition to the senior team.
"We had some close games and our record might have been better, but I think overall, it was most important the players progressed in their own ability and learning of the game.
He added, "It was also their first chance for them to be coached by myself in a tournament situation, so I also learned a few things about them too."
And if some of the under-20 rising stars take further steps forward during the forthcoming club and college seasons, then perhaps one or two who stepped out in Bulgaria might just have a shot at forcing their way into the reckoning for EuroBasket Women 2015.
