Williams said "I think everyone would agree that the sides at the top of the National League would be able to compete comfortably in League Two.
"I think often teams can get bogged down in the EFL and in a bad place and ultimately drop out of the league, and once they get themselves together and reborn, we have seen this quite often in recent seasons and try to build themselves back up.
"Clubs like Notts County, Chesterfield, and Wrexham have huge fan bases and as soon as they get going correctly again, they become a real force and would strengthen the competition in the EFL if two or three sides were promoted.
"Of course I am biased, but I do genuinely believe that the standard is so high at the top of the National League that it would strengthen the EFL if they allowed more teams to go up and compete there."
