Context paragraphs:
Peter Jackson (footballer, born 1961): Peter Allan Jackson (born 6 April 1961 in Bradford, England) is a football manager and former footballer.  He has previously had two spells as Huddersfield Town manager, whom he helped win the Division Three play-off in 2004, and he has also managed Lincoln City, before taking charge at his former playing club Bradford City in 2011.

2004–05 National Division Three South: The 2004-05 National Division Three South was the sixth season (18th overall) of the fourth division (south) of the English domestic rugby union competition using the name National Division Three South.  New teams to the division included Lydney who were relegated from 2003–04 National Division Two as well as Havant (champions) and Hertford (playoffs) who were promoted from London Division 1 while Reading came up as champions of South West Division 1.  The season would also see the introduction of a new points system with 4 points being awarded for a win, 2 points being awarded for a draw (replacing the old system of 2 points for a win and 1 for a draw) with the addition of a bonus point being given for scoring 4 or more tries as well as a bonus point given if you manage to lose a game within 7 points of the victorious team.  In terms of promotion the league champions would go straight up into National Division Two while the runners up would have a one game playoff against the runners up from National Division Three North (at the home ground of the club with the superior league record) for the final promotion place.

1997–98 Huddersfield Town A.F.C. season: The 1997–98 season was a disaster turned into a success for Huddersfield Town.  After a closed season of little activity in the transfer market, Town started the 1997–98 season disastrously and, after some questionable signings and tactical decisions, Brian Horton was sacked in October 1997 as the club lay at the foot of Division One.  Thirty-six-year-old former Huddersfield, Bradford City and Newcastle United central defender Peter Jackson was drafted in as Horton's replacement in October and turned the club's fortunes around drastically.  He immediately installed the experienced former Wales manager Terry Yorath as his assistant.  Given a generous transfer budget by the board, Jackson captured experienced pros such as former Welsh internationals Barry Horne and David Phillips in addition to powerful local-born striker Wayne Allison from Division 1 rivals Swindon Town.  He also managed to rejuvenate players such as Marcus Stewart and, particularly, the previously inconsistent Paul Dalton to the extent that the club finished a respectable 16th in the final table.

2010–11 Huddersfield Town A.F.C. season: Huddersfield Town's 2010–11 campaign was Huddersfield Town's seventh consecutive season in the third tier of English football.  After losing to Millwall in the play-offs in the previous season, many hoped that Town would gain promotion to the Football League Championship this season.  After finishing in 3rd place with a club record of 87 points, the Terriers lost the play-off final at Old Trafford, by 3-0 against Peterborough United, meaning that they would stay in League One for another season.

2008–09 National Division Three North: The 2008–09 National Division Three North was the tenth and last season (twenty-second overall) of the fourth division (north) of the English domestic rugby union competition using the name National Division Three North.  The division was set to be re-branded National League 2 North for the following season due to an RFU reshuffle of the entire league system.  New teams to the division included Halifax and Nuneaton who were relegated from the 2007–08 National Division Two while promoted sides included Loughborough Students who came up as champions of Midlands Division 1 along with Kendal (champions) Huddersfield (playoffs) coming up from North Division 1.  A further, final change to the division saw Rugby Lions transfer across to 2008–09 National Division Three South as the most southerly side in the division in order to address a team imbalance between the two leagues.  The league system was 4 points for a win, 2 points for a draw and additional bonus points being awarded for scoring 4 or more tries and/or losing within 7 points of the victorious team.  In terms of promotion the league champions would go straight up into what would be known as National League 1 from 2009-10 but unlike previous years, there would be no promotion playoff between the runners up of the division and the runners up of National Division Three South due to the league restructuring.

New teams to the division included Rugby Lions who were relegated from the 2003–04 National Division Two while Bedford Athletic were promoted as champions of Midlands Division 1 along with Bradford & Bingley (champions) and Cleckheaton (playoffs) who both came up from North Division 1.  The season would also see the introduction of a new points system with 4 points being awarded for a win, 2 points being awarded for a draw (replacing the old system of 2 points for a win and 1 for a draw) with the addition of a bonus point being given for scoring 4 or more tries as well as a bonus point given if you manage to lose a game within 7 points of the victorious team.  In terms of promotion the league champions would go straight up into National Division Two while the runners up would have a one-game playoff against the runners up from National Division Three South (at the home ground of the club with the superior league record) for the final promotion place.

The league system was 4 points for a win, 2 points for a draw and additional bonus points being awarded for scoring 4 or more tries and/or losing within 7 points of the victorious team.

In the case of Luton, Midlands league champions usually moved up to National Division Three North but due to number imbalances in that division, for this season, they would go into National Division Three South instead.  The league system was 4 points for a win, 2 points for a draw and additional bonus points being awarded for scoring 4 or more tries and/or losing within 7 points of the victorious team.  In terms of promotion the league champions would go straight up into National Division Two while the runners up would have a one-game playoff against the runners up from National Division Three North (at the home ground of the club with the superior league record) for the final promotion place.
