Dude, he had a .667 TS% for the day on that volume. It's not like he took 52 shots to get 44 points, it was 31 shots (and fouled twice not counting the and-1s, for 33 total "possessions ending in a scoring attempt") .667 is ridiculous efficiency, particularly at that volume, for a guard. League average TS% is about .560. Volume-shooting guards that aren't great at threes don't come close to .667. Kobe never touched .600 for a season. Jordan snuck past .600 four times, never crossed .620. And those guys were averaging low-to-mid 20s in FGA per game - that's high enough volume to start bringing down your efficiency. Your classic volume scoring guard - Allen Iverson - was at .518 TS% for his career. There may be others, but the only guard I can find who has put up .667 TS% for a season is Steph Curry, who has edged past that mark twice (both times he led the whole league in TS%) and that was on 20 or fewer FGA.
Dismissing Fox's DAY - not his season, not his career, but THIS DAY - as "volume scoring" is absolutely comical. Not unexpected, but comical.
You didn't watch the game, did you?
