Only Barnsley signed more loan players than Doncaster Rovers in League One last season.
The Tykes brought in no fewer than 15 loanees - and are preparing to face Millwall in Sunday’s play-off final.
Rovers signed 14 and dropped into League Two.
Oldham Athletic, who climbed out of the drop zone towards the end of the season, also signed 14.
Rochdale, who finished tenth, signed the fewest (three).
The next lowest (four) were Sheffield United, Port Vale and Millwall, who all finished in the top half of the table.
Football League clubs will have to adhere to new loan rules from next season onwards. Emergency loans have been scrapped and only half-season or season-long loans will be permitted.
Rovers have relied heavily on the old system as a means of bolstering numbers and covering for injuries. They have signed more than 50 loan players in the last six seasons.
That trend continued under Darren Ferguson, who signed 11 players on loan following his appointment in October: Chris Neal, Remi Matthews, Felipe Mattioni, Craig Alcock, Tommy Rowe, Conor Grant, Cameron Stewart (loan extension), Eddy Lecygne, Riccardo Calder, Gary McSheffrey and Lynden Gooch.
League One loans (in final position order): Wigan 11, Burton 7, Walsall 5, Millwall 4, Bradford 10, Barnsley 15, Scunthorpe 6, Coventry 12, Gillingham 9, Rochdale 3, Sheff Utd 4, Port Vale 4, Peterborough 8, Bury 12, Southend 9, Swindon 10, Oldham 14, Chesterfield 6, Fleetwood 9, Shrewsbury 8, Doncaster 14, Blackpool 10, Colchester 6, Crewe 8.
