It was reliable for Rick Barry:

When he retired, he was the career leader in FT% for both the NBA and the ABA. You seem to value the aesthetics more than the results. IT may not be for everyone. Sure, guys like Steph Curry are better off shooting with the same motion as their regular shot, but for guts like Shaq, Ben Wallace, Andre Drummond who flat out suck at the line, t the point they become a liability with the game on the line, it can improve their percentages. No one is saying guys who shoot well should switch, but guys who suck at FTs should consider alternatives, if they care more about winning thane being teased.
Rick Barry was one bad ass dude who gave ZERO fucks about what anyone else thought. Teasing didn't bother him so nobody bothered teasing him. Plus, it's pretty hard to tease the guy who was THE best FT shooter in the league (both of them) for his entire career.
Serious question: game on the line, score tied. A Blazer player is at the line, with one shot for the win. Would you rather he shot underhanded and made the shot, or shot overhanded and missed it? Would you be so embarrassed by winning on an underhanded FT that you'd rather risk losing than win in such an unmanly way?
Would your opinion change if it was Game 7 of the NBA Finals? If the Blazers won an NBA Championship on an underhanded FT would you hang your head in shame, or celebrate our first championship in over 40 years?
