Just watched these highlights – https://www.youtube.com/watch?v=C1YFqqD6po8.
Like most bigs at this level he looks like a bit of a project, but he has a huge frame and wingspan, and it looks like he moves pretty well for his size. Long Beach Poly is also one of the best athletic high schools in the nation and Johnson has been playing excellent high school competition in SoCal. His lack of offers is a bit of a mystery – and while he missed most of his jr season with injury- there isn’t much about his performance over the summer in AAU ball.
Makes sense to prioritize another big given the injury concerns with Sedore (and Lieb to a lesser extent).
