Manning stopped in to see him recently.
247 is reporting him at 6'5" 250. Hudl has him at 6'4" 240.

watch those highlights. He's a soph so it's a long way to go but he looks like an absolute plug. I laughed at a couple of the highlights because offenses looked comical against him. I'm not sure about his competition in this film (everyone looks small in comparison) but I'm almost positive that Booker T Washington plays pretty decent teams from the Hampton Roads area.
