Now, Lyles wants to learn more about the rest of the U of L staff and see the campus. So he's scheduled an official visit to U of L.
The 6-foot-9 Lyles, who is ranked as the No. 4 player in the '14 class by Scout.com, will make a visit to U of L on Aug. 31. Tom Lyles, the player's father, confirmed the visit and said the family is "really looking forward to it."
"It gives him a chance to meet everybody and allow him to get a feel for what everything looks like and feels like," Tom Lyles said. "They have a great staff at Louisville. It's a great basketball staff.
"But this gives him a chance to meet the ones he's only talked too (on the phone or through text) and a chance to meet everyone on the administrative side and the academic side. And that's important.
"You have to put the pieces together and make sure it's a great fit."
Lyles is down to four schools, including U of L, Kentucky, Florida and Butler. He will visit UK on Oct. 18 and will visit the other two schools but no firm dates have been finalized between the two parties.
Tom Lyles said the official visits will be "very, very crucial" in the decision-making process for the family.
While publicly Lyles isn't claiming a leader or a group of leaders, the perception is that the Lyles recruitment will come down to a battle between the last two National Champions – Kentucky and Louisville.
Trey Lyles told Scout.com in July that all four schools were "really equal," and his father told Cardinal Authority that his son was "really open."
Lyles played AAU ball with U of L commitment JaQuan Lyle. Another AAU teammate – James Blackmon Jr. – recently de-committed from Indiana and has offers from both U of L and UK.
"The visits are (important) because he needs to understand what expectations will be placed on him as a freshman," the father said.
