Iain Henderson believes there is room in the Ireland camp for both the highly excitable and the cool and collected types.
The Ulster captain has always come across as a laid-back figure and admits he is able to motivate himself for the big games without hopping off the walls or demanding to know where people's "f***ing pride" is.
Former Ireland prop Mike Ross revealed years ago that Henderson, who made his debut in 2012, was known as 'The Llama' when he first arrived into camp "because he would just wander around the place".
The 28-year-old is in line for his 58th cap should he make Andy Farrell’s squad, named after lunch today, for Saturday’s Autumn Nations Cup match at the Aviva (2.15pm, live on RTÉ2).
When fully fit, Henderson is James Ryan’s most likely partner in the second row and has a string of dynamic performances under his belt, none of which come, however, on the back of raised voices or manic impassioned speeches.
"I think most people you talk to would say I’m a relatively calm individual," said Henderson, who was named man of the match in last Sunday's disappointing win over Georgia.
"I don’t get fired up very often. And when it comes to games, it’s time to work, I suppose.
"There are a lot of guys who get really fired up in training and fired up when they don’t get things right, whereas I definitely try to bring a more calm approach.
"There’s a lot of boys when they’re captain will really rile things up and get shouting and yipping and yawing, and I think that works well.
"Sometimes that works for me - other guys doing it. I’m not that type of character. As a captain, I do rely on players doing that.

"When I captain Ulster, I do rely on certain players stepping up to do that; certain players riling those types of boys up. It’s definitely a mix.
"If you had a team full of people who are calm and level-headed and don’t shout, you might end up being very flat all the time.
"However, if you end up with a team full of people who like to scream and show how passionate they are through that, you might end up with a team who get very angry with themselves and flustered quite a bit.
"So, I think you need a balance of people who can lower the emotion level a wee bit and bring everything back to basics, but on the flipside of that have people who can fire people up and bring people along with them."
The bookmakers are struggling to pick a favourite between Ireland and Scotland, with the visitors hoping to end a 10-year drought on Irish soil.
Scotland centre Duncan Taylor believes there is a real battle at hand.
"They are a great side, a side we have struggled to beat in the last few years," said the 31-year-old Saracens man, who has won three of his 27 caps against Ireland.
"They will bring a strong attacking game, they will bring a few surprises I would imagine off first phase, they have a great defensive unit and they have guys who are good over the ball and make the breakdown a bit of a nightmare.
"I think we are going to see a real battle at the breakdown, and they have some great individuals who can cause problems, so we will have to be on the money at the weekend."
