You truly never know who is going to pan out at the next level, and sometimes it can be hard to determine exactly where and how a rookie is going to fit onto your squad on and off the floor.
This doesn't seem like it will be a problem for Cooper Flagg and the Dallas Mavericks, though, as Dereck Lively II recently revealed exactly who Flagg is, and Mavs fans are going to love him. After Lively II hosted a basketball camp at the Mavs' practice facility earlier this week, he was asked about Flagg, and his comments about his personality are what make him special and set him apart from other rookies.
