I honestly don't think he's in. Mitch Richmond has 20,000 points, and despite playing for a non-playoff team for the majority of his career, made it out of the 1st round twice in his prime and won a ring in his twilight. 6 time All-Star 5 time All-NBA...not in
Tom Chambers hit 20,000 points and isn't in. Cliff Robinson and Terry Cummings hit 19,000, Bernard King has a scoring title and 19,000+ points and isn't in.
Tracy has 18,000, and yes a nice prime, but he's never made it out of the first round of the playoffs.
All those other guys scored over or nearly 20,000 points, had All-Star level stretches of their careers but when all is said and done....they're not in. Tracy's resume doesn't really separate himself from that pack, in my opinion.
Terry Cummings scored over 23 ppg for 5 seasons in his career and slid way off due to injuries, like McGrady. He never won a scoring title, but was an All-NBA player in his prime, still had a nice post injury career and netteed 19,440 points and played in 110 playoff games. Including playing in Western Conference Finals and averaging over 20 ppg in earlier career playoff runs when his team had advanced past the first round.
Injuries can de-rail a hall of fame career and having a nice 6 year run can be forgotten. No one remembers Terry Cummings averaging 23 and 11 as a rookie, that doesn't make him a lock. McGrady shouldn't worry about getting into the Hall of Fame, if it happens, it happens, but I don't think anything he did separates him from the players I've listed.
