I myself have gone from 6'2.5" to 6' and i also have regular back issues, but to die at 2M he was still one hell of a big man. I believe when he left school he was 6'11 and not finished growing. By WM3 you could already see he was suffering physically and was nowhere near his stipulated height but regardless, he was in the top 1% of human beings for height. No doubt.
