If Curbelo leaves, that gives me more faith that Kofi is back. Brad could only build his offense around one of them, and he chose the rock solid dependable one. If Kofi were leaving, i would expect a less half-court focused team with more transition and less lane traffic - a much better fit for Dre's game. Watching Miami's tourney games where they have thrived with undersized guards, i can see why he might be interested.
I will not blame Brad one bit on this one. Curbelo had the longest leash i've ever seen. People were complaining last year about Curbelo being wild in the Duke game and i commented that we were good enough that Brad could let him work out the kinks in a game at Duke. I know it was post-concussion, but Curbelo was given chance after chance in the Marquette game to the point that even before the game ended i had chalked it up as a sacrifice Underwood was making for Andre's development. There is so much that we don't see, but what i have seen has been nothing but support from the staff - within the context of a style built around Kofi.
