"The Lions are phenomenal. We should not even be discussing [the tour being the last].
"It is all very well talking about that if you are 12,000 miles away, and I understand the arguments in terms of a global season. But this tour is what rugby is all about.
"I love the professional game and everything about it, but we need to be a little bit old-school occasionally. The Lions are very much part of our history and the fabric of what we are.
"I have never seen Eden Park like it was last week - a sea of red for an All Blacks game, which was bizarre. It says a lot about the Lions supporters and how good they are."
Current All Blacks captain Kieran Read also endorsed keeping the concept alive when addressing the media on Friday, rejecting suggestions that a poor result for the Lions in the second Test and overall in the series would kill off future tours.
"I don't think that will happen," Read told reporters. "It has just been so exciting being around the country over the last couple of weeks and seeing the supporters from both sides. The fans are so passionate about the game. I'm sure it will continue."
Fitzpatrick went on to criticise national newspaper the New Zealand Herald for their clown front-page of Lions coach Warren Gatland earlier in the week, while adding that the Lions had a better chance of winning the second Test than the first encounter at Eden Park.
"I was so disappointed on Tuesday with that clown front page about Gatland, purely because it has no reflection at all on what the tour has been like," explained Fitzpatrick.
"The anticipation here is still that the Lions could win, which is phenomenal when you consider how well the All Blacks have been playing.
"I said from the start the Lions will not win the first Test. But potentially, if they get it right, they could win the second one."
