Yes it is. the question on whether he will make 15000 is another matter but he is clearly the one really world class opening batsman england have had in a long time.
we've tried a lot with him and honestly none are a patch on him in form. I would say if he's got any sort of form he's assured of his place.
on a side note... england look 50% of a great side. anderson and broad are the clear no 1 bowling attack, but the issue is woakes and stokes developing. Moeen isn't up to it as a main line guy but he's streaky. he needs to make it with bat.
root is the other top class player then so hales, compton, vince.. we just need peopel to set up and fill in the batting line up and bolwers find more consistency.
