Loony Bob, I'm not sure that you really seem to appreciate that the differences between the county/domestic game and the International sphere are huge.
Attributes that will gain success in one won't necessarily do so in another, and while 80mph seamers may be devastating on green-tops against India, on less friendly pitches against batsmen who've seen that sort of bowling since they were 10, it's not going to make as much difference.
See the whole Harmison debate that's gone on for the last year and a half - poor domestic record, talent and attributes (height, pace, bounce) there for coaches to see, International success - the same story goes on with a lot of International players.
Butler, as well as having pace, also has more height a la Harmison and so will add an extra dimension to a fairly similar Kiwi attack.. but it's not like it's really going to make any difference, is it?
