Not sure about the worst start, but overall Drury is easily the worst manager in the history of Boston United FC. The previous worst was Neil Thompson with 26 wins in 84 games giving a win percentage of 31%. Drury has 2 wins in 13 games giving a win percentage of just 15% or twice as bad as the previous worst!
Don't worry though I'm sure it will get much better in the long run. Have faith. Trust me I'm a mathematician.
