The next tour being SL should help Foakes get in the side, Butler is ahead of Bairstow for me but has not really done enough these last 6 months to be an automatic pick.
Long term thou England's green shoots of a batting recovery may help Foakes .. burns, Sibley, Crawley have done well and we now have a specialist batsman at number 6(fantastic). Dom Bess can def bat so if he plays in Sri Lanka the batting looks OK to me.
Yes the keeper has to score runs and Foakes is decent,so if you look at the last 3 years how much runs have we really got from the batsman/keeper position?
Not enough to justify a batsman who keeps doing the job...
Time for a long term change of thinking whether it's home or away.
I'm a bit biased, along with the top 3 I believe the keeper should be a keeper first, as in a specialist. Foakes is a pretty good bat as it happens as well but there's no one even close to him for keeping- he is as good as we have had since Jack Russell.
