The Hawks made two moves Monday. They signed Jabari Parker, who in 2014 was the NBA’s No. 2 overall draftee, and dumped Omari Spellman, on whom they spent a first-round pick only last year. On a scale all but broken by the weight of KD/Kyrie-to-the-Nets and Kawhi/George-to-the-Clippers, these didn’t really register. But they were, shall we say, intriguing.
