Isnt it obvious ?
We have always been a good L1 side but now we are crap. Gary Johnson got us into the championship and pretty much held us there until we got rid thinking we could do better, since then it's just been 3/4 years of sh1t
That would only mean something if they were all managing same club at the same time in the same division, Holloway has mostly managed in Prem or Champ whereas Cotterill was with Cheltenham
