"It's not something you think you're ever going to attain in your rugby career," Read said. "It's certainly amazing, and a great feeling.
"It was probably a couple of weeks ago that [coach Steve Hansen] told me I was going to be the one leading the team. There's a leadership group there; we knew it [the captain] was going to come out of that. The group that we have there is still going to do what they've done for the past few years and I guess I'm the one with the 'c' next to my name. The responsibility is to really step up and lead this side really well."
Asked about the pressures that go with the role, Read said: "I think it will be tough because I haven't experienced it yet. Certainly, you can probably tell there's a bit of pressure there and it's probably one of the most important roles in New Zealand sport and I'll find out in the next few weeks."
Read, whose head knock and sore shoulder meant he didn't play in the second half of the Crusaders' 23-22 win over the Waratahs, said he would be fine this week.
As for whether McCaw had given him any advice, Read said: "Not too much, he's left me to do my thing."
Hansen insisted Read wasn't the only potential captain the selectors looked at: "We considered a whole lot of people," he said. "But ... we felt he had the necessary attributes and character that we were looking for."
