Say what you will about Conor McGregor but he certainly isn't a shrinking violet.
It was noted just seeconds into his UFC debut in Sweden against Marcus Brimage in 2013 by commentators Mike Goldberg and Kenny Florian exactly how calm the Irishman was in a scenario that would have sent most other human beings' pulses racing but, judging by the video below, it doesn't seem that McGregor has ever displayed any real sense of nerves prior to a fight.
A user on Reddit MMA compiled a video of McGregor's ring introductions over his ten or so most recent fights, ranging to his days in Cage Warriors all the way up to last March's clash with Nate Diaz and it's incredibly interesting to see McGregor develop over the years.
From his early Cage Warriors days, to his first fight in the UFC, through Chad Mendes and Jose Aldo and all the way to Nate Diaz, it is fascinating to watch both McGregor and, even more interestingly, his fanbase develop over the years.
And, don't forget, another introduction will presumably be added to this compilation next weekend in Las Vegas at UFC 202.
