In our old adult ‘grass-roots’ league, Gloucester 2, a local team called Tredworth had a fearsome (and deserved) reputation for bringing violence to the pitch. They also had a violent set of travelling fans that would get involved if anyone stood up to their abuse. Most normally bouyant clubs would struggle to raise a 1st XV on the league weekends when it was a Tredworth game.
In fact my last ever game was against Tredworth I came off after 60 minutes exhausted and smashed up. Crap way to end playing a game I absolutely love.
They folded last year thankfully, and the local leagues collectively breathed a sigh of relief, even though it was actually a shame as the club was 110 years old and wasn’t always that way
EDIT: You didn’t wanna run the touch-line at a Tredworth home game I can tell you.
