Maverick. Noun. An unorthodox or independent-minded person. In Fantasy Rugby, such a quality is potential gold-dust.
It should not be confused - as it often is - with mercurial, an adjective to describe someone who is subject to sudden or unpredictable changes of mood or mind.
Mavericks are those players whose rugby brains run so fast that their team-mates, and even occasionally their own feet, sometimes struggle to keep up.
They're the Freddie Michalaks, who could also lay claim to 'mercurial', the (not initially selected, shame on you Eddie Jones) Danny Ciprianis, the Brian O'Driscolls of this world. Players who can, could and did change a game in an instant by off-the-wall thought or breathtaking deed or sheer force of will.
Rugby is a technical game. There are many skills drilled into you so you can do your job really well all the time - click here for our nation-by-nation selection of the brightest players in the 2019 Six Nations. But - and this is the joy of it - there's still room in all this training for that second of mind-blowingly brilliant maverick in-game madness that alters everything.
Here, then, are five mavericks you may have ignored - or maybe hovered over before going for someone else - when selecting your initial squad who could do something spectacular and rack up serious Fantasy Rugby points in the weeks ahead.
Jonathan Joseph - England
A late call-up to the England Six Nations set-up, less than a week after playing his first 50 minutes of rugby in nine months for Bath against Toulouse in the Champions Cup. His last cap came at the end of last year's Six Nations and he is England's joint top try‑scorer in the Jones era. Admittedly, Joseph faces strong competition for the 13 shirt from Henry Slade and Manu Tuilagi - but if he gets the nod for Ireland, he could rock this Six Nations, and send you soaring up that Fantasy Rugby league.
Gael Fickou - France
Since moving to Stade Francais, the Frenchman has rediscovered the joie de rugby that was a hallmark of his game when he first broke through. But there's a problem for anyone dreaming of a Fofana / Fickou French midfield pairing. It comes in the XXXL form of Mathieu Bastareaud, who apparently has first dibs on that 13 shirt. If Fickou does start, chances are he'll be out wide, but - even there - you can expect him to come looking for work ... and if he gets those feet dancing, defences could be in deep trouble.
Finn Russell - Scotland
Yes, we keep banging on about Russell and how unconventionally brilliant he is. But, admit it, you've all gone for Johnny Sexton at 10, haven't you? That's very sensible but, if you're looking for an edge, it could be a tactical error at the same time. You'll gain no fly-half advantage over anyone in your Fantasy Rugby mini league picking the same guy as everyone else. Take a risk. Russell may not be as consistent as World Rugby's Player of the Year, but when the mood takes him - and the mood has taken him plenty over in France this season - he's maverick poetry in motion.
Steff Evans - Wales
It wasn't that long ago that the hot-stepping Evans' World Cup hopes seemed to have faded as he slipped down the Wales back-three pecking order. So, now, he has made it into the Wales Six Nations squad, he will be out to give Warren Gatland a serious nudge that he deserves a seat on the plane to Japan - and that could mean breaks and tries aplenty to set your Fantasy Rugby scoreboard rolling...
Will Addison - Ireland
We had Jacob Stockdale down as one of our maverick choices last year - which worked out very well, as after a very quiet opening match, he ran in a Six Nations record seven tries. This time, we've gone for the silky-running Ulster centre, who made his debut as a replacement in Chicago in November. Breaking the Henshaw-Ringrose double-act in midfield is a tough job, but Addison has what it takes - and is a real threat with ball in hand.
