Now I know stats don't tell everything, but I think those say a lot.
There are lies, damn lies and truths. That particular set, IMO, is a set of damn lies. It mixes time-periods and is a good example of manipulation.
The simple fact is that Butcher only had one good spell in his Test-career before 2001 (since which he has played 30 Tests, being a designated opener in just 4 of them), during 1998 when he played South Africa then got a 116 at The 'Gabba. Other than that, batting in a variety of positions including one, three and six, he failed pretty solidly.
Since his recall in 2001 he has looked very much the most solid batsman in the side, whether batting one or three. It's just 26 out of 30 Tests have been at three so lots of people, unfortunately for a time including himself, have got the misleading impression that he's better at three than he is at one.
The fact is there's not a massive amount of difference - Butcher's no inferior at three to at one, but Vaughan IMO is far better at four than at two, and Trescothick's never been anything but an opener, though he doesn't mind whether he bats one or two.
