Rotherham's first game of the season was played on 18 August 2012, versus Burton Albion, in their new home; which was requested by chairman Tony Stewart because of the homecoming occasion.
Before the season began, the club were tipped by many bookies to lift the League Two title, leaving newly promoted Fleetwood Town and local rivals Chesterfield in their tracks.
United were also tipped to be one of numerous favourites to contest the Football League Trophy, however they were out in the first round prior to a 1–0 defeat to York City.
However, this season's away top is a thick, black bar across the chest, with the badge on the left, Puma logo in the centre and the town crest on the right.
The first training session of the season was held on week commencing 2 July 2012, 13 days previous to the first pre-season fixture against local team Parkgate.
It was a vital time, as the players got a long jog and light training to get back into the football routine; as well as meeting the summer recruitments.
The opponents in these games, of which were two Yorkshire rivals in Barnsley and Doncaster Rovers, would stage 6,000 and 9,000 maximum capacity matches respectively.
The 2012 Scottish Cup champions Hearts, and local rivals Sheffield United would both stage maximum (12,000) capacity matches, also respectively.
Comments from other supporters suggested that the players brought in were Championship quality, and would tear other teams such as Barnet and Accrington Stanley to pieces.
