3 out of 3Maddie Meyer/Getty PhotosScottie Barnes, PF Florida StateAlthough Cunningham Green, Mobley, and Suggs are the top four prospects at the moment, they aren’t the only ones that lottery teams are interested in. For example, the No. They are actively considering the next level of prospects and have selected No.The Cavs are considering Jonathan Kuminga, a G League prospect, and Scottie Barnes from Florida State, as potential players."They will do their homework to expand the No. Chris Fedor, of Cleveland.com, wrote that the No. 3 search will go beyond Cunningham and Mobley, Green, and Suggs. "...Some of these guys, including Kuminga, will conduct predraft exercises in Cleveland before July 29.Kuminga may be a bit of boom-bust prospect due to his poor shooting technique, but Barnes is a great two-way player and is a safe option for anyone who lands him.Derek Bast, NBADraft.Net's writer, wrote that "He handles and plays the ball well and can post up low against larger defenders." His versatility on offense matches his versatility at the other end.Barnes, a "solid two-way player", may not be the best choice for casual fans. However, he would make a great addition to any NBA roster.Jalen Johnson (SF, Duke)Jalen Johnson from Duke is a similar player to Kuminga. He has an unfinished shot which will keep him out the top five. He has the size, athleticism, court vision, and court vision to be a key role player. Johnson isn't a star but there's still a lot to be gained from that.Wasserman wrote that Johnson still intrigues him most in this group with his open floor handle, passing on move and face-up agility as a 6'9" (220-pound) strong athlete." I believe that he will find ways to score and make plays with his open-floor handle, passing on the move and face-up agility for a 6'9" tall, 220-pound strong athlete. He can also drive past bigs and cut, finish, and find teammates.Johnson, who averaged 11.2 points and 6.1 rebounds this season, can be a valuable asset to teams. Johnson is a high-floor prospect that could be valuable to playoff-caliber teams who are looking to trade up.Johnson won't be the headliner of this year's draft class but he is NBA-ready and will add immediate value.Keon Johnson, SG/SF TennesseeTennessee's Keon John is another high-floor prospect. However, he could be even more at the next level. Wasserman says that a team will need help to improve Johnson's offensive skills to unlock his full potential.Wasserman wrote that he did move him back a couple of spots based on his distance as a shooter and creator at Tennessee. He has the athleticism, passing, and defense to be a high-level player, but will need significant skill improvement to reach a ceiling that is comparable to a top-option scorer.Johnson, who averaged 11.3 point in 25.3 minutes per contest last season, could still be a plug-and-play rotational player for a playoff contender. According to Ian Begley of SNY, the New York Knicks could package the 19th through 21st picks and the 32nd picks to get into the top eight.Johnson will likely be a key player in his early career. Johnson could be a star if he can improve his offensive skills.
