In addition to UNC, King, a 5-foot-11, 175-pounder, is garnering attention from Clemson, Florida, Florida State, Georgia, South Carolina, Tennessee, and Wake Forest.
"There's a lot of talk," Miller said. "A lot of guys are interested – he's getting a lot of letters, but no offers have come up, yet."
Just about every interested school has asked King to attend one of its camps this summer. He has yet decided which camps he'll attend.
King, who isn't in a rush to make a verbal commitment, doesn't have any favorite schools.
"I'm going to wait until I visit all of them and then I'll figure out what I'm going to do," King said.
One of King's more recent visits was to UNC for the Tar Heels' Spring Game, two weekends ago.
"It was a good experience," King said. "I talked to all the coaches; they seemed pretty nice [and] they all knew me."
King has also visited Clemson, Florida State, Georgia, South Carolina, Tennessee, and Wake Forest.
After posting gaudy numbers in the junior varsity ranks, King was brought up to varsity midway through his sophomore season. He went on to start Byrnes' homecoming game against Spartanburg High and registered two catches, both touchdowns, for a total of 52 yards. He ended that season with eight catches for 159 yards and three touchdowns.
Last season, King became a fulltime starter playing slot in Byrnes' pass-heavy spread offense. He ended the season with 29 catches for 462 yards and four touchdowns and was named third team All-State.
"Jazz is one of those clutch guys that doesn't mind going across the middle catching the football [and] doing the things he has to do to make our offense go," Miller said.
This fall, King will be moved to outside receiver where he hopes to replace Mississippi State signee Ricco Sanders as the go-to target.
"The outside receiver runs pretty much fades and checks," King said. "And the slot basically goes through the middle."
