I think my concerns about referees in League 2 (and from what I've seen on the televised live games throughout the EFL) is that they seem to let a lot more go than their colleagues in the Premiership. Is it just me or would there have been far more fouls (and cards) if the Mansfield (and I understand Newport) game had been either in the Prem or refereed by one of their officials?

The laws of the game are the same, but their interpretation seems different.
