i just saw an interview with Blount by Alex Donno (posted to youtube 3 days ago). Donno asked him his height and weight and Blount said "6-4 and I just weighed in today at 272".
Does anyone have a confirmed date (or year) of birth? i might have missed it in this thread. Someone said he is reclassifying to return to his normal grade (which would make him presently 17/18). Thanks!
