Enda McEvoy: How come Tipp haven’t won the MacCarthy Cup in successive seasons since 1964-65?

Right, that’s today’s gag done. Still, before readers from Bansha to Ballingarry get themselves into a lather they might try responding to a simple question. (The answer is not a simple one, admittedly.) How come Tipp haven’t won the MacCarthy Cup in successive seasons since 1964-65?
There’s a chap out there who thinks he knows. It’s the “complacency they suffer from in Tipperary”, he says. The “typical Tipperary softness that creeps in over the winter months and that’s very hard to arrest”. Their tendency to “celebrate too long and too hard”.
