Lions captain Brian O'Driscoll has endorsed Gavin Henson's criticism of Sir Clive Woodward's preparations for the Test series in New Zealand.
O'Driscoll and Woodward worked closely during the tour
"There are certain parts of his argument you could probably agree with," O'Driscoll told BBC Sport.
"I wouldn't agree totally with it all but there are aspects Clive himself would probably change if he could.
"You don't have to be brilliant to realise the Test team probably needed to play together a bit more often."
Welsh star Henson criticises Woodward's preparations, tactics and game plan in his new book, serialised in a Sunday newspaper.
He may risk disciplinary action after breaching a gagging order, which does not expire until next week, on players criticising aspects of the tour for a period of 100 days.
O'Driscoll's own Lions recollections will be unveiled in a book published later this month.
"The surprise aspect Clive was trying to work on didn't exactly work as it was meant to," O'Driscoll added.
"That is something I am sure he would change if he got a second opportunity but they don't come along if you are talking about the Lions and playing New Zealand.
"Hindsight is a fantastic thing and you are going to see a number of different opinions over the course of the next month when the ban is lifted about talking about the Lions.
"There will be some interesting views and I have my own angle on things. You will have to watch this space."
Henson also takes a swipe at unnamed squad members in his book, which O'Driscoll believes he may regret.
"I don't think you do yourself any favours by giving it out about team-mates in a book, rather than saying it to their face," he added.
"I've got some comments to make on how I thought the tour went, but none of them criticising any of my team-mates. It is more objective, the way I look at it.
"I felt we had a genuinely very good opportunity of going down to New Zealand and winning a Test series - I truly believed that.
"When you look back, we didn't get some of the components right to enable ourselves to do that."
O'Driscoll will miss Ireland's entire autumn Test series as he recovers from a disclocated shoulder sustained in the first Test against the All Blacks.
But he could be back in action before Christmas, in time for the end of the Heineken Cup pool stages in January and the RBS Six Nations starting in February.
"I am not putting an end date on it because I don't want to disappoint myself," O'Driscoll added.
"But the rehab is coming on really well and I feel week to week it is getting progressively better.
"I hope to be playing in the not-so-distant future."
