It was me that referenced that stat from Twitter, I think someone here might have read it wrong.
The stat was that only 2 of their last 7 managers have won all Irelands, not that the 5 managers directly before Cody failed to win one.
Of the 5 that didn’t win, Derek Lyng is one. The 2 prior to Cody (one being Nicky Brennan, I cant remember the other name) also. Before those 2 was Ollie Walsh who won 2 All Irelands as someone else mentioned. And before Ollie Walsh there were 2 more that never won an all Ireland, one being Eddie Keher.
So in the last 40+ years there have only been 2 KK managers who have won all Irelands, Cody and Ollie Walsh.
Now stats can be misleading at times, as that sounds like a terrible return, until you consider one of those 2 successful managers has won it 11 times. So it certainly wasn’t me throwing any stones at KK, it was just a surprising one to read.
