Can you comeback in 6 Nations matches?


Watching yesterdays Ireland vs Scotland game as Ireland built a first half lead I couldn't help but think that I'd struggle to name many Six nations matches which the half time leaders did not go on to win.
Rather embarrassingly I realised that I'd seen the biggest comeback in the Six Nations the previous week as France surrendered a 16-0 lead against Wales. However by that point I was already ferreting through some scorelines.....

So how often are there comebacks in the 6 Nations?

Answer: In 292 matches in the Six Nations era there have only been 46 comebacks from a half time deficit to win.



Put another way 81% of the time the team winning at half time go on to win

This graph rather neatly shows how common it is for teams to be winning at half time and go on to win. Home teams who have achieved this are in the top right quadrant, away teams in the bottom left, the away teams who have comeback are in the top left and home sides are bottom right.




The 2011 championship was the high point for comebacks with 5, however for 3 years between 2002 and 2005 there were no second half comebacks at all.



Margins for comebacks


As you would expect the size of the half time deficits does affect the chances of a comeback. If you can stay within six points at half time you have a decent chance, but the value of leading by a converted try does seem to have a significant impact; leads of less than six points have been overturned 30% of the time, but leads of 7 of more just 6%.




This demonstrates the outstanding Welsh comeback in Paris last week, as its one of only 4 come backs in the 6 nations era from a decifit of 10 points or more. The question is can you name the others (answers at the bottom).

But who are the comeback Kings? And who cant be trusted to finish the job?



Answer: Wales have staged the most comebacks (12) after being behind at half time, followed by England on 9. France and Scotland are next with 8 each.
On the flip side the stereotype of the mercurial French would appear to have a few grains of truth in it with Les Bleus having been the victim of 11 second half comebacks closely followed by Scotland and Italy with 10 each.

Of course this is possibly a bit unfair on France - how often have Italy led at half time in comparison?

So looking at the rate of second half comebacks - its actually England top of the pack with a comeback rate of 23% compared with Italy's rate of just 5%.


TeamComebacksComeback Rate
England923.08%
France821.05%
Wales1220.69%
Ireland514.71%
Scotland812.12%
Italy45.06%

England also lead the way for closing out a game when they lead at half time only having lost on 4 occasions, Italy once again are bottom of the table losing after leading at half time 40% of the time.


TeamLeads LostLoss Rate
England46.35%
Wales68.70%
Italy510.00%
France1115.94%
Scotland1026.32%
Ireland1040.00%

Taking this a bit further leads to an interesting little fact:

There is only one Six Nations fixture pairing that hasn't seen a second half comeback to win: Ireland and England, the reverse of this is the Scotland and Italy games see a second half comeback once every three matches on average.


Conclusion


So in short, second half comebacks are really difficult to execute in the six nations and the value of a 7 point lead is not to be under estimated.

And those 10 (and above) point comebacks in the Championship since 2000?
England (17) 17-18 (6) France 2005
England (16) 19-26 (6) Wales 2008
Italy (13) 20 - 21 (3) Scotland 2014
France (16) 19-24 (0) Wales 2019

In other words half of the half time leads England have frittered away to end up losing are 10 points or more!

How many points = automatic promotion in the football league?

Its very much that time of year, where for those of us with a vested interest any Saturday afternoon glance at some football scores leads onto some hurried mental arithmetic as we try and work out whether the season in which we've already invested emotionally and financially will end in glory or not. As a Luton Town fan I have some 'skin in the game' again this year, and therefore for the past few weeks I've been trying to work out whether or not the Hatters are on track for a second successive year.... what follows is some of my workings. How many points do you need to get promoted in the English Football League?  We'll start by comparing the points needed for the title and promotion in each of the EFL's three divisions and see whether any division is 'easier' to win (in terms of points scored, obviously the championship is the hardest to win from a purely footballing point of view). For the sake of simplicity throughout this blog I'll refer...

Premiership rugby's rarest scores....

The rarest scores in premiership rugby A few weeks ago I looked at some of the most common scores in premiership rugby, this time I'm looking at some of the rarest. The first place to start is by defining rarity so we'll look at those scores with the lowest frequencies. We'll also look at relative rarity. Rugby's rather peculiar scoring system means that some adjacent scores are much more likely than others. For example in 25 seasons premiership rugby teams scored 9 points 100 times but 8 points 194 times and 10 points 218 times. The rules At this point I should say that I've excluded those impossible scores 1, 2 and 4. I suppose those scores are rare, in the sense that you are unlikely to see them.  But the comparison I'd use is that you wouldn't describe a Dodo as rare and like a Dodo these scores are extinct for now.  I also excluded the Covid walkovers. Whilst there were scorelines given they didn't happen.  I've used scorelines from the 25 seaso...

2019/20 for Exeter Chiefs in the Gallagher Premiership (so far) - featuring some TREEMAPS!!!

With the Gallagher Premiership returning from its extended break due to the Coronavirus this weekend I've dusted off some player stats for the first 13 rounds of the 2019/20 season. As part of moving from 'analyst of data' to 'Data Scientist' I used a new tool (or rather perfect slightly something I've been playing with for a while), I've been toying with the R package "treemapify" to make some visualisations for a few months now and thought this might be a good use for them.  Treemaps are very simple - the bigger the area the bigger the proportion of a total made up by that element.  I think Rob Baxter's preference would be defence first so the first graphic shows the number of tackles made in the Premiership so far by each Chiefs player who has featured (nb this excludes missed tackles).  Unsurprisingly the largest areas are those forwards who play the most and its reflective of how little the likes of Henry Slade and Jack Nowell have feature...
