Nwankwo will get 10-15 minutes a game unless Konate and Diedhiou never see the court at the same time again. Weather they play together or not, its a virtual guarantee that these two will average 7-9 fouls between them every game.
FWIW - Pitino has said that he will play Konate and Diedhou together. Sounds like Gaston can also slide to the 5 as a backup. I'd guess you are right about Nwankwo's time. Regardless, I am hopeful that other teams do not get as comfortable driving the lane next year as they did last year.
