Star Welsh outside back Liam Williams has admitted that it has not always been easy in the Lions training camp with the players having to learn a new way.
The lions take on Japan on Saturday before setting off to the tip of Africa where the World Champion Springboks lie in wait.
"There's a whole new playbook. It will take us more than a couple of weeks to get that spot on," Williams said to walesonline.co.uk.
"I have been calling some of the calls we have with Wales, the Scottish boys have been calling some of their calls.
"It's exciting seeing a whole new playbook in team meetings, but to put that into practice it will take a couple of weeks.
"Every individual is completely different in how they learn. I could sit on a laptop for 10 hours a day and it just won't stick in so I need to be doing it on the training pitch."
