"I had no intention of committing today, it just blew me away. I felt like it was a great opportunity for me," he said.
"The coaches, the facilities, the players they're bringing in, and just everything. I feel like it's a good deal here."
"I just decided to commit, I felt like it was the right thing to do. I want to be back with my coach, the one who got me into this position I'm in now," he said.
Causey is now at Fort Lauderdale (Fla.) St. Thomas Aquinas and so is his fellow FAU commit, Jordan Scarlett. Harriott was a huge reason they picked FAU. Causey says Scarlett's commitment to FAU back in December also had an impact on his decision.
"He was a big factor because we always planned on going to college together, so I guess it's coming true," Causey said.
Of the four commits in FAU's 2015 class, three are former University School players. Harriott lead that team to a state title in 2012 and Causey is confident that this same group can do it again.
"We're trying to build a legacy, we're trying to do something special. This isn't just an ordinary class," he said.
"We did it at U-School."
The Owls have a lot to look forward to in the 6-foot, 193-pound corner.
"They'll get everything that they want," Causey said.
"I'm just another player on the field, doing my job."
Causey said he'll likely still take some visits, South Carolina being one of them.
