But the Argyle boss, who has led his club to next Monday's League Two play-off final, says any move to a structure that has five divisions made up of 20 teams must be looked at carefully.
"There's no doubt from a coaching point of view having 38 games rather than 46 is beneficial to a manager," he said.
"But it's not beneficial to the revenue of a football club."
He added to BBC Sport: "They're going to miss out on four home games, so to speak, so that's where it becomes a wee bit difficult."
Under the proposals, which were unveiled by the Football League last week, an additional division would be created if 90% of the organisation's 72 clubs agree to the plans at the 2017 annual meeting.
If they go ahead there would be no relegation from the current League Two in the 2018-19 season and eight teams would join from the National League.
Plymouth Argyle manager Derek Adams says plans to expand the Football League will be beneficial for managers.
