His Twitter announcement put previous contenders Baylor, Indiana and Kentucky on the outside looking in, though truthfully none of those three had received much buzz in recent weeks. Alexander is amid a slate of fall visits, and some believe that the Illini, Jayhawks and Spartans hold the lead.
2. Trey Lyles said on Monday that he's down to Kentucky and Louisville. That news surprised exactly no one, and in fact the Wildcats are such prohibitive favorites that an undecided top-10 prospect is getting unusually scant media attention. The Cardinals are the defending champions and can offer much of what UK can, however, so perhaps there's at least some reason not to pencil in Kentucky just yet. Still, don't expect many takers on that action.
3. Rashad Vaughn won't be visiting North Carolina officially this weekend, as had been scheduled, though he does intend to visit Chapel Hill at some point during the season. The Minnesota native recently hasn't been linked as closely to UNC as he had earlier this year, as Iowa State (Nov. 8 official visit), Baylor (Oct. 19) and UNLV (nothing planned, but he's attending nearby Findlay Prep) appear to hold the edge.
