Kansas head coach Bill Self announce two signings on Thursday.
"Joel's potential is untapped," Self said of Embiid. "I think he's just now starting to figure it out and get confidence. He will develop and be one of the very best tall guys in college basketball in just a year or two. The way we play, we can move him around and he made me a much better coach when he put his name on the dotted line."
Talking about Greene, Self offered: "Brannen is one of the most skilled 6-foot-7 guys in the country," Self said. "He can shoot it. He can put it down. He's got good vision. He's a guy that should have a smooth transition from high school to college, in large part because he is a big guard. He's not a guy that has been playing inside a lot."
The Jayhawks also received a letter of intent from ESPN 100 PG Conner Frankamp (Wichita, Kans./North) on Wednesday. They are also expecting letters from ESPN 100 SF Wayne Selden (Boston, Mass./The Tilton School) and PG Frank Mason (Petersburg, Va./Massanutten Military).
