The 6-foot-10 forward from Indianapolis (IN) Arsenal Tech put out on Instagram that his final four were Kentucky, Louisville, Florida and Butler.
UCLA and Duke had previously been on his list.
“Kentucky gets players to the league faster, but Louisville might develop them just a little bit better,” Lyles told Jeff Borzello of CBSSports.com.
Lyles on Thursday night went for 21 points and 14 rebounds as Spiece Indy Heat beat Team Final, 69-68, at the Peach Jam.
Kentucky coach John Calipari, Butler coach Brandon Miller, Florida’s Billy Donovan and Louisville assistant Kevin Keatts were all on hand.
Lyles averaged 20.3 points for Canada in the recent FIBA U19 World Championship, good for third best, and is part of a new wave of elite Canadian talent that includes recent No. 1 draft pick Anthony Bennett and presumed 2014 No. 1 pick Andrew Wiggins.
