Cousins has until Monday to register to play in a state league, which could pave the way for an AFL return next season.
On Tuesday, Flying Start Management boss Ricky Nixon told the Herald Sun it was "more likely than unlikely" that Cousins would head east and play in the VFL this year.
But on Wednesday, Nixon said Cousins should be wary of returning to high-level football.
"To come back at this stage is probably just to get on the training track," Nixon told Melbourne sports radio station SEN.
"To play football is a massive step again and to play at a level like AFL level is a decision that will have to be made down the track some time. I’m not convinced that that is the right thing for him and that’s a personal view.
"I think it's a longer shot than what everyone thinks," he added.
"Not because he's not capable of playing, but you've got to understand he hasn't played for a couple of years really, he only played I think eight games last year.
"So by the time you play AFL football, which will be April next year, I think it's at least a couple of years since you've played AFL football.
"But there's no doubt someone of his ability could have a much better chance than most."
Cousins was deregistered by the AFL for 12 months, preventing him from playing in the competition, following revelations last year about his drug addiction.
Flying Start Management representative Carlie Merenda flew to Perth for talks with Cousins ahead of Monday's deadline.
"Carlie will be in Perth over the next four or five days doing a number of things for Ben, a part of which is informing him of the processes that need to be put in place by Monday, if he wants to play footy," Nixon told the Herald Sun.
"That's something Ben will have to make a decision on over the weekend, which includes which state, which club, etc etc."
Cousins, who is based in Perth, could register to play in the WAFL.
AFL chief executive Andrew Demetriou and AFL Victoria chief executive Peter Schwab both welcomed Cousins' possible return to the field.
