Grant defended the ARL Commission's attempts to limit the earning capacity of NRL rookies as negotiations continue over a new collective bargaining agreement.
The Rugby League Players' Association is philosophically opposed to capping salaries but Grant said it was a sensible way to fix to a clear problem.
"The fact is we take young men in our game away from their homes too early, we put them into intensive competitions, we ask too much of them and quite frankly we've had some disastrous outcomes," he said.
"That's all about giving them expectations beyond what is reasonable at the time and frankly paying them too much money will do that.
"We understand the RLPA's situation and we've got an obligation to negotiate with the RLPA around these sort of things. But by the same token, we're really trying to respond to the issues we've got."
Meanwhile, Grant indicated a name change may be on the cards for the NSW and Queensland Cups as their current monikers don't "ring true" given the level of current and future international involvement.
The Papua New Guinea Hunters have played in the Queensland Cup since 2014 while the entry of a Fijian team into the NSW Cup is expected to be approved in the coming weeks.
"What it does for PNG is fantastic, rugby league is their national sport and it really means something to them. It's the same with Fiji," Grant said.
"We have players in our NRL competition that come from all of those places and we've got to make sure they've got local rugby league that they can see that's at the elite level."
