Cork V Waterford: Five things we learned

The sweeper system works

Things happen in big games.

Call it the Harold Macmillan Syndrome. “Events, dear boy, events.” With 51 minutes gone Cork were a point up, 0-15 to 1-11. Then Damien Cahalane was shown a second yellow by James Owens for his high tackle on Conor Gleeson. Dismissals don’t always decide matches — a minor branch of literature has been devoted to teams who won big games with a man sent off — but Cahalane’s banishment went a long way towards determining the outcome.
