Jos Buttler.

Don`t quite see where you`re coming from here.    Fielding standards have improved immeasurably as the years have gone by, which makes it all the more surprising that it`s taken 150 years for someone to do what Buttler`s done.

Alf, you may not be aware of this little known fact, but in the old days cricket pitches/fields were twice the size of the modern ones, thereby making it more difficult to hit 4's and 6's. This probably accounts for those old players missing out on T20 hundreds. I have read one account of WG Grace hitting one ball and then running an EIGHT with his partner. Before the next bowl was bowled he demanded to have a fag break to recover.

...added to the fact that one day First Class cricket only started in the 1960s and First Class 20 over stuff in the 2000s. I don’t need to speak for bluetornados but I presume that’s what he means.
But I guess alf is correct that it’s surprising no one else has done it as we’ve had a few decent one day players, Hayles, KP to name a few. Am sure others could be mentioned.

Now that is the million dollar question how to turn his one day form into test match form, you’re right.

I think they tried what you’re suggesting with Jason Roy the last time the Aussies were here by getting him to open the batting. It didn’t work but Buttler is better so it’s worth considering. Surprisingly I don’t think Jos Bs average in all the forms is wildly different. In the 30s in all three forms. They tried him opening a few years ago but if failed he got under 10 runs in 4 innings, two tests. His averages when batting at No 6 is the best, high 40s, so I’d be surprised if they did change him from No 6. In Australia if he opened the Aussies would put 5 slips/gully in place then get Hazelwood and Starc to attack the off stump and nail him in the first half hour, esp with the bounce on Australian pitches. In Sharjah the bounce is poor and the wickets slow generally.

I think Buttler scores fairly well behind the bat so he would be vulnerable. I get all your points in favour of it and you may be right and we have struggled with openers so it may be considered but I think the selectors like the reliability of Buttler at No 6 in test cricket. He holds the middle and lower order together and an average of 47 ( I checked) at No 6 is good. 
It seems incredible doesn’t it that we absolutely hammered the Aussies in the T20 match but they’ll start as clear favourites for the test matches because the pitches will be totally different?

The first officially recognised Test match took place between 15 and 19 March 1877 and was played between England and Australia at the Melbourne Cricket Ground.

The international one day game is a late-twentieth-century development. The first ODI was played on 5 January 1971 between Australia and England at the Melbourne Cricket Ground.

The idea for a one-day, limited 50-over cricket tournament, was first played in the inaugural match of the All India Pooja Cricket Tournament in 1951 at Tripunithura in Kochi, Kerala. It is thought to be the brain child of KV Kelappan Thampuran, a former cricketer and the first Secretary of the Kerala Cricket Association.

Twenty20, a curtailed form of one-day cricket with 20 overs (120 legal balls) per side, was first played in England in 2003.

The first T10 competition using this format took place in December 2017, the opening season of the T10 League in the United Arab Emirates.

100-ball cricket (2.5-hour games), another form of one-day cricket with 100 deliveries per side, launched in England in 2021.

Plus there are many other forms of cricket too,  WG Grace, Wally Hammond, and Jack Hobbs would probably created many records if these other cricket types had been around.

True Somerset lad, born in Taunton. He also played for Glastonbury, I presume after Cheddar. Somerset never wanted him to leave but in 2011-13 found themselves with two top, top players both who wanted to play for England as a wicketkeeper. With Kieswetter a key member of the England T20 World Cup winning team he was probably favourite for the keeper spot being there before and the player in possession as it were. Jos played as a batsman and kept wicket when Craig K was on England duties. Then he left at the end of 2013, all amicable and 6 months later Kieswetter had a career ending injury. So in 2014, Somerset found themselves with no keepers after having two world class players months earlier. Sod’s law!!
I actually think he will end his career back in Taunton when he retires from England duties.
