"North Carolina is a big[-time] school, but I was more comfortable with Florida State," Echefu said. "I was more comfortable with the Florida State staff."
The decision was finalized this morning, according to Montrose coach Stu Vetter, and the coaches were notified at 1 p.m.
"I was just sitting there [last weekend] thinking about it," Echefu said. "There's no doubt they're both good schools but there's just little things that made my decision."
But the long-lasting relationship with the Seminoles staff was the ultimate reason why he'll be enrolling at Tallahassee this fall.
"It was the relationship he developed with the coaching staff [at FSU] over a three-year period," Vetter said. "I think that was a big factor.
"Obviously with the recent developments with the North Carolina program and the players all declaring for the draft, they became a much greater opportunity for him, but the fact of the matter was that Florida State had been recruiting him for a long time."
The other finalists, eliminated a couple weeks ago, were Maryland and Kentucky.
"Carolina is a good school and one of the top programs in the nation," Echefu said. "They came and talked to me and I really considered them a lot. But I just looked into what I think will be best for me and that's why I made my decision [to go to FSU].
"Each coach told me about the playing time, but I didn't take that into consideration because everybody plans to walk-out and play," Echefu continued. "You have to earn it. I'm going to work hard to earn it."
Echefu's senior season stats at Montrose were 20.5 points (59% FG), 11 rebounds, and two blocks. He won MVP honors at the Capital Classic national all-star game, posting 18 points (8-11 FG) and 7 boards.
Echefu is ranked the No. 11 power forward by Scout.com in the senior class and No. 37 overall.
