Rees-Zammit said the latest three-day camp with the full Chiefs roster had meant a chance to “dive deep into the playbook”.
“It’s been a good week overall and definitely helped doing rookie minicamp, getting reps, because the way I learn is actually doing the reps,” he said.
The Chiefs have listed Rees-Zammit as a running back, but the four-cap British and Irish Lions wing still believes he could feature as a receiver in the future.
“I’ve been put in the running back group to start with,” he explained.
“I think there’s going to be a versatile role for me, I’m hoping. The coaches are very creative here, so see what they can do. But it’s all about me learning the playbook and learning the game because without that I can’t do anything else.
“I am fully focused on the now. You know, I’ve got to make the team. How am I going to do that? I’ve got to perform on the field, I’ve got to learn the playbook and then we’ll go from there.”
The ex-Gloucester wing, who scored 14 tries in 32 Tests for Wales, feels his current role will help ease his transition from rugby union.
“Being in the running back position it’s easier because I can get the ball earlier as opposed to being out playing wide receiver,” he added.
“It’s obviously different and catching – you catch laterally in rugby, you don’t catch forwards. That’s been a bit different.
“I’m just loving being able to work and work on all these crafts because the more I can do, the more I can try and help the team.”
