Sexton is only 19 and his one weakness is outside shooting -.336 from 3-point range.
Sexton worked out for the Cavs at their training facility and owner Dan Gilbert referred to the 19-year-old as "a very interesting draft prospect" on Twitter. The confident 6-foot-3, 190-pounder is a proven scorer and he addresses a major need for the Cavs, who traded All-Star point guard Kyrie Irving to Boston previous year.
The pick comes two years and two days after Irving hit the biggest shot in franchise history with a go-ahead 3-pointer in Game 7 of the 2016 NBA Finals, assuring the Cavs their first championship.
James was on family vacation during the draft, multiple league sources told ESPN, and the Cavs entered Thursday without being informed of James' intentions for next season.
Whether LeBron James decides to leave Cleveland or remain with the Cavaliers, they will likely revamp their roster after getting swept by the Golden State Warriors in the fourth chapter of the NBA Finals matchup.
Rather, the addition of Sexton is the latest step of the Cavs toward a different era not seen since the days when Irving was drafted first overall in 2011, up until LeBron James returned in 2014.

Mnangagwa told state broadcaster ZBC, without elaborating, that those responsible must have come from "outside Bulawayo". Mnangagwa, who was rushed away from the scene of the explosion, later visited the injured in hospital.
Their only pure point guard on the roster is 32-year-old George Hill, so Sexton is a fit.
Since James and Love's arrival in 2014, the Cavs have been to four straight Finals and won the first National Basketball Association title in franchise history.
Altman said he has had "really good dialogue" with James' management team.
"My problem toward the end of my career was I was trying to shut everybody up and I was greedy (to win more titles)", O'Neal said to ESPN Friday.
It appears the Cavaliers are doing everything they can to keep LeBron James. Perhaps this player offers new options on the trade market, or perhaps this player is actually good enough to contribute, even though Ty Lue doesn't like playing rookies. We don't take him for granted.
He is just too risky for me. If the Cavaliers are not looking to deal Sexton, they have very little capital to acquire a player of Walker's ilk. "I'm going to come in and learn and be the best player I can be on the court as well as off the court". But they can work a deal with Team X before the draft to select Player Y and then immediately trade Player Y's rights to Team X for an established player.
While Sexton certainly improves the Cavs' backcourt and adds a young player capable of breaking down defenders, there is no guarantee it will do anything to impact what James will do.
