Dolly has featured in over 40 games on his first season back at Mamelodi Sundowns, in addition to his national U-23 and Bafana Bafana commitments.
The former Ajax Cape Town man remains active in the CAF Champions League, and is expected to play a key role for Owen da Gama's side at Rio 2016.
Buckley, who was part of Shakes Mashaba's U-23 team that beat Brazil 3-1 at the Sydney Olympics in 2000, doubts Dolly will struggle with the workload.
"It is his job and I have been there back in the days. I also didn’t have any breaks. I would have to come back to the national team and play pre-season and play again," Buckley tells snl24.com/kickoff.
"I didn’t have the break. At the end of the day it is your job and you are a professional footballer and that is what professional footballers do. You must be there 24/7. When you get called up to play for the national team you must be there and play.
"He’s a very young player and you don’t get that burnout. If you guide him properly like now I’m sure in Brazil it won’t be intensive training. It will be just to maintain the team, getting the right shape on how to play and who to play where to win every game that comes along," concludes the AmaZulu assistant coach.
