Listening carefully during our interview, it seemed Burnham had distinct gears. He was fluent and passionate on his familiar ground: his desire to sort out social care, his track record in Manchester, his desire to run a government that feels relevant and effective where you live, local leaders eager to make many more decisions and able to spend taxpayers' money more freely without permission from Whitehall.
Those are his core beliefs, arguments he's made hundreds, if not thousands of times.
But when it comes to how he'll apply what he thinks in principle to what he does in practice, that was not always so clear. On social care for example, he's long believed there ought to be a National Care Service, like the NHS. But in a speech on Wednesday, that's not likely to be what he unveils.
Instead, he told me he'd "brought it straight forward", understood to mean speeding up the government review by Baroness Louise Casey of what ought to be done, not saying, "here's the plan".
When it came to questions that are on his desk for the first time, there was a contradiction. Burnham told us all many times that he will stick to the manifesto the country voted for in 2024.
But he's also vowed his arrival in office will usher in the biggest change in four decades. You don't have to be a student of political history to find a mismatch there - he's going to stick broadly to Sir Keir's plan, yet shift the government more fundamentally than leaving the EU, or the financial crash? Really?
And beyond the rhetorical tension in several areas, Burnham gave clear indications that he will apply "new eyes". Will he stick to the home secretary's plans to make migrants wait 10 years or more before they can permanently stay in the UK? He's looking at that again he told me, and hinted that care workers could possibly be exempt.
But when it comes to the gravest matters that prime ministers have to deal with - security, power around the world, or the country's long-term economic stability, we're perhaps yet to see if Burnham's ambition for No 10 is accompanied by truly new big ideas that match the scale of his rhetoric.
There are worries on the right of the Labour Party that Burnham has not absorbed the reality of the country's economic position - years of stuttering growth, and sky-high levels of debt that leave the UK incredibly vulnerable to the financial markets' judgements, whether he likes it or not.
And concerns on the left, that he's tickled their bellies with promises of "authentic Labour", flirting with the ideas of increasing state control of vital industries, but which might not come through. And like most incoming prime ministers, he has precious little experience of handling international events. The moments in our interview where he was least sure-footed were answering questions about how he'd manage relationships with Donald Trump and Vladimir Putin.
One minister said he'd "vibe left, but govern from the centre". Perhaps, as he's tried to give firms and families a "breathing space" when it comes to the cost of living, he'll ask for "breathing space" from the public before his complete programme becomes clear.
Burnham has long been unusual as a politician - a leader who has managed to be popular in a time when politicians often disappoint and are sometimes despised. He knows he's walking into a job that's been marked by failure for a decade. As he told me, "the onus is on me not to be another one who just doesn't change things". He's part of a political generation he proclaims to be "just not good enough".
Remember, his own career has had plenty of failure too. It took Burnham three goes to become the leader of his party. As he arrived, straightening his tie, to be confirmed in the top job in central London 10 days ago, I asked him why he'd taken so long.
He laughed and told me, "I like to make an entrance".
Andy Burnham has now truly arrived. But he knows all too well, there won't be applause everywhere he goes.
