Duke has the longest-tenured staff currently recruiting Purvis and also brings a lot to the table, according to Rodney.
"They have great coaches. Coach K really lets his guards play," Purvis said. "I can get a great education. It's also close to home for me."
Missouri recently hired former Miami coach Frank Haith, but added a more important component in Purvis' recruitment by adding former Louisville assistant Tim Fuller, the lead recruiter for Purvis when he was committed to the Cardinals.
"(Missouri) lets their guards play. Coach Frank Haith is a good guy; I'm really getting a good relationship with him," Purvis said. "Of course I have a relationship with (assistant coach) Tim Fuller. The players there are also really great and really cool."
North Carolina State has also gained ground in the recruitment under new head coach Mark Gottfried.
"The NC State staff has been really aggressive with recruiting me and I've been over there a couple times," Purvis said. "I'm just trying to build a relationship with them. That's close to home for me too."
While it's been rumored that Purvis currently has a favorite, he quickly refuted the rumors to TDD and broke down the timeframe on his recruitment.
The February decision would seem to indicate a spring signing, but Purvis didn't rule out the possibility of committing earlier, as well.
"It might be (spring)," Purvis said. "If it just gets too hectic, then I'll just go ahead and pick a school."
