If someone were to argue McGinnis was the best player to ever come out of the state of Indiana who contributed at every level of basketball within Indiana? I don't think there's even a debate about it.
He's definitely in the mix as one of the best to come from Indiana at all without the qualifier. Oscar Robertson is probably the only one who is hands down better. Larry Bird is more famous, but was nowhere near the player McGinnis was at the high school level if you're approaching the argument from that angle.
Led Indy Washington to just the second undefeated state championship season. First to score 1,000 points in a season, set the Final Four scoring record and had that legendary performance mentioned above in the Indiana-Kentucky game when it mattered.
Averaged 31 ppg in his lone season at Indiana University, the year before Bob Knight arrived.
It's a shame he's remembered as a mercurial Sixer. He's on the Mount Rushmore of ABA players at 25.2 ppg, 12.9 rpg, 3.5 apg. Led the Pacers to two of their three ABA titles. The NBA deserves a lot of scorn for the way it treats the historical record of the ABA. Players like McGinnis kept swept aside as footnotes. He was arguably the best non-Kareem player in pro basketball from 1972-77-ish.
RIP.
