I think it was because Blackpool picked up no points from the game. You can't be seen to benefit from playing the player I guess (see Hartlepool being docked points against Brighton before then). The only one that sticks out is the Sunderland one when they played one in about five games and made a Wembley final on the back of their cheating. Though most of that was the Premier League rather than the Football league, and it was MK that missed out in the cup, so I think that is fair enough.
Division 3 could be very Northern looking next season. Rotherham, Wigan, Blackpool, Dale, Fleetwood, Barnsley, Badfud, Doncaster, Scunny, Vale, Crewe, Sheff Utd/Chesterfield, possibly Preston yet, Shrews, Bury, Burton (alright, pushing the Northern bit there).
