24 refs are officiating at their current level, for example SG1 for a tie involving at least one PL club. 7 are 'punching above their weight' - Barrott, Brooks, Speedie, Stroud, Coy, Drysdale and Harrington, and just one - Kevin Friend - could be said to be refereeing at a lower level, although Chorley v Derby (on BT) is undoubtedly a key tie. A good mix of SG1, SG2 and FL refs, and it tends to be the 4th round before most if not all ties are refereed by SG1 refs.
