Both JJ and AI have officials lined up for the next 4 and 2 weeks, respectively. So based off of that, I'm going with AI, who will be open to making a decision by Sept 20 or so. JJ's last official takes place in October. (AI's random unofficial visit looks like it could have been a silent commit, but wants to go on some officials at UW and Oregon)
Also wouldn't surprise me to see the staff sneak Grimes or Clarke on to campus (according to 247, neither have visits lined up) in the next couple and get a commit. The Nwankwo commit puts a lot of pressure on the last available targets.
I love how this staff makes offers, and takes the commit. No funny business.
