This set contains all 14 teams that competed in the top level of rugby league in England, with all teams getting home and away team ratings, as well as scoring cards including try scorers and goal kickers.
 
Due to a lack of data, this set doesn't include individual goal kicker ranges, and team kicks at goal have been estimated using the 1989 Australian League data.
 
Wigan wrestled away the title from Widnes, ending their two year run as champions, as they finished four points clear of Leeds. Four teams all finished two points further back. It was Wigan's eleventh championship.
 
At the bottom, Barrow only won one match, and were relegated along with Salford and Leigh - who finished in the drop zone on points difference behind Sheffield, who were forced to spend most of the year out of the city following the Hillsborough Stadium football disaster.
 
Widnes did make it a three-peat (and sixth overall) win in the Premiership Trophy end-of-season tournament for the top eight league finishers, beating Bradford 28-6 in the final.
