Promoted sides Bristol Rovers, Exeter City and Forest Green Rovers will raise the level of competition in League One next season, according to Morecambe manager Derek Adams.
The top half of the third tier was fiercely contested last season, with the top 11 all picking up at least 70 points, while Plymouth Argyle agonisingly missed out on the play-offs with 80. At the other end, the bottom six clubs, including Morecambe, were cut adrift from the rest, with the Shrimps and Fleetwood Town doing just enough to survive.
But with three big clubs – Derby County, Barnsley and Peterborough United – dropping into League One from the Championship and three strong teams – plus one of Port Vale or Mansfield Town – joining from League Two, Adams is expecting an even tougher task when the campaign begins in late July.
