Coaches have been in the news recently. First, Andy Farrell will succeed Joe Schmidt as Ireland’s coach after the World Cup. This should make the 2020 Six Nations England-Ireland match an interesting family affair, with father Andy coaching Ireland and son Owen , one assumes, captaining England.Then there is a rumour that the RFU is considering asking Warren Gatland to be Eddie Jones’ successor when the garrulous Australian moves on. It was long assumed that Gatland’s ambition was to be the next coach for his native New Zealand. So it may be that he would be interested in the Twickenham job only as the next best thing. This is something that presumably wouldn’t commend him to the RFU. If, however, he does land up at Twickenham, he will have been pretty well round the houses as head coach of Ireland, Wales and England, and, twice, of the Lions. Meanwhile the Welsh Rugby Union has already appointed another New Zealander, Wayne Pivac, to take over from Gatland next season.
