"The Crusaders were well-stocked, clinical - and they took it to us. When you have a team like that they will punish you and once the momentum got going it was difficult to stop."
There was some slim hope that Rudi Wulf or Chris Lowrey might return from the injured list while Benson Stanley was out with concussion and probably would miss the rest of the Super 15 season.
"It is a concern, another concussion and he's had a few now. He has not had one this year, but on the back of last year with Auckland when he had that last one, there is concern.
"The medical team are monitoring that and there are protocols."
Asked if Stanley could be forced to sit out the whole season, Lam said: "There is a good chance, - it is not definite. We just have to prepare, that could be the case."
The All Blacks will return to the group tomorrow. Lam said that at this stage of the season there would be no problems slotting back into the Blues' routines.
Ali Williams, Ma'a Nonu, Piri Weepu and Tony Woodcock would return and be part of the selection for the duel with the Highlanders.
The visitors won tough against the Bulls and would be another awkward rival who would test whatever resolve the Blues had left this season.
