Wests Tigers head coach Michael Maguire believes NRL athletes should be ready to play at a week's notice, with the league suspended indefinitely due to coronavirus.
The NRL postponed the season on March 23 amid the COVID-19 pandemic, which has brought sport to a standstill across the world.
Only two rounds of the 2020 season were completed when the league was put on hiatus and the NRL is determined to resume the campaign in some form.
As the competition faces an uncertain future, Maguire told NRL.com: "If we only had a week, you'd play in a week.
"Is that the right thing for their bodies at that time … it's not ideal. Yes, in our game it would be handy to have a lead-in and all those things to get our players back.
"From a sports science view they'd want to have a month but if we got to September and it was getting tight and we were ready to go, I can't see players not wanting to play.
"It's their job to look after themselves during this period. That's the expectation in professional sport, the players that do it better than others will go on and kick on when the season starts and create opportunities for themselves."
Maguire, whose Tigers won one of their opening two games, added: "If you went away and did it you'd succeed and if you didn't you found you weren't playing at the top level.
"It's a learning experience for the young guys to see what it used to be like. We didn't have all the coaches or the facilities that we have, we had to rely on ourselves. Some did it well and others didn't.
"They're men and this is their trade so I think if they take responsibility and look after themselves they'll be in good shape by the time it comes back.
"I think every coach would've been talking to their players about that.
"There's a lot of chatter around gym equipment being moved into player's garages and everyone's training but that's the expectation of a professional sportsman now.
"If you're not then you're not going to have the career you thought you would."
