Sir Graham Henry, the only man to coach both the All Blacks and the British and Irish Lions, says Warren Gatland's squad will potentially embark on a "suicidal" itinerary in New Zealand.
The Lions, who will arrive in the country on Wednesday, May 31, four days before their first match against the New Zealand Provincial Barbarians in Whangarei on June 3, also face the Blues, Crusaders, Highlanders, New Zealand Maori and Chiefs before the first test at Eden Park on June 24. Their next match is against the Hurricanes before the tour finishes with two more tests.
Gatland will announce his squad in London tomorrow and Henry said while the 37 players will be thrilled to make the tour, all of the fixtures will be extremely challenging.
"I know from my own experiences how much the players respect getting selected for the Lions," Henry told ESPN. "It is the pinnacle of their career. It is massive but they need to do well and I just wonder if the itinerary is suicidal. That is my concern.
"They are playing New Zealand Maori, they are playing the five franchise teams - and those five franchise teams have nothing to lose, no pressure on them at all, so they will fire everything at the Lions and take them on.
