"It took a while to get my head around to the fact that I'd be on the wing," the Scarlets veteran admitted. "I've only played there once and that was years ago for Pontypool. I remember playing against Nigel Walker, who was in the Wales team at the time, and just tackling him whenever it looked like he was about to get the ball!
"All of Saturday was a little surreal for me, and to be part of a Grand Slam-winning side is a dream come true."
The 32-20 victory gives Taylor forty-nine caps for his country, but he's not sure where number fifty is coming from.
"If you look at the midfield resources Wales have, with Tom Shanklin and Gavin Henson looking like a Lions pairing and Sonny Parker coming back, there's not a lot of room for me," said Taylor. "I think I'll have to start poisoning some of the competition to get my fiftieth cap."
Taylor, 30, says retirement is not something he's thinking about.
"I won't retire - they'll have to retire me. When you've been through the bad times with a team, you don't want to leave during the good times."
Taylor said the Grand Slam was "just the start" for the young Wales side.
"They're such a talented bunch, with such a great spirit, you can only see them getting better and better," he said. "Getting the Grand Slam was amazing and it was incredible to see the trophy in the Wales changing room, but this is just the start."
Taylor said he and a few team mates went into the Cardiff city centre late on Saturday to soak up the atmosphere and had the place to themselves!
"We weren"t mobbed or anything," he said. "By the time we got into town everyone was too sozzled to recognise any of us."
