Cooper Flagg, the second-youngest player ever drafted No. 1 overall, had a standout rookie season with the Dallas Mavericks that drew frequent comparisons to LeBron James' debut campaign with the Cleveland Cavaliers back in 2003. While Flagg's Mavericks struggled to a 26-56 record, his individual stats were neck-and-neck with the young LeBron's, including nearly identical scoring averages and rebounding numbers.
