Not every broken record needs an asterisk. Don Freeman took 595 shots in 65-66. Shannon has taken 400, so far. Freeman averaged 25 shots a game, which would lead the NCAA this season, by a LOT. The NCAA leader this season takes 19. The high major leader, RJ Davis, takes 16.4 shots a game.
The game has changed in numerous ways, yes there is a 3-point line, but there was also a propensity for teams to revolve their entire offense strategy around one person in those days. You just don't see usage like that these days.
