Mike Hall Jr. is selected 54th overall in the second round of the NFL draft by the Cleveland Browns.
Judging by social media posts, it appears Braxton is an Advocare distributor: https://www.advocare.com/150370655/Mobile/Default.aspx
(there's more pics of his reppin but can't post from my mobile - but seems legit it's THE Braxton Miller)
