The insiders are just guessing, but this seems pretty simple to me. Bolden apparently wants to play for Calipari. That's why he hasn't announced yet. If Bolden wanted to play at Duke, he could have announced weeks ago because Duke already has an open scholarship for Bolden if he wants it. Kentucky does not have an open scholarship for Bolden. Here is the math. Matthews, Hawkins, Mulder, Briscoe, Fox, Monk, Willis, Wynyard, Lee, Humphries, Adebayo, SKJ, Gabriel. That adds up to 13 full scholarships, and that's why Bolden has not been able to commit. With Calipari's encouragement, Bolden has been waiting and waiting for a scholarship to open up at Kentucky. At some point, a scholarship might open up at Kentucky, or else Bolden will eventually tire of waiting. Nobody knows how much longer Bolden is willing to wait. If Bolden gets tired of waiting, he might take his plan B option by picking Duke. That's a pretty good plan B. But IMO, if Bolden picks Duke, that would simply mean Calipari wasn't able to open up a scholarship for Bolden at Kentucky. He has obviously waited this long because he knows Calipari and Payne are the best in the business at preparing bigs to play in the NBA.
