The series ended in a 1-1 draw after a thrilling Third Test ended 15-15 at Eden Park, Auckland, last Saturday morning and that result means Sam becomes the first Lions skipper to remain unbeaten over successive Test series, having led Lions to victory in Australia in 2013.
It's also only the second time the Lions have avoided series defeat in New Zealand - the only victory back in 1971.
Speaking immediately afterwards, Sam said: "It's difficult as players when you go through all the pressure and the emotion of the week, it's all geared towards winning, but it's better than losing I guess!
"We've come to the double world champs and what they've done here over the years has been incredible so to not get beaten is something we can take credit for. It was a great Test match to be involved in.”
Sam - a former schoolmate of Gareth Bale at Whitchurch School, Cardiff - told us back in 2013 how he came to support Spurs.
"My father was born in London and made me and my twin brother Ben support Spurs from age six when I got my first shirt. He would always tell us 'you're Spurs in the blood now boys!' He had supported the Club most of his life too."
