What is sporadically? If you hit 50% on one of every 4 occasions and hit 25% on 3 of 4 occasions, your average is no where near 50% (I'm a little tired and had a few beers so I don't want to do the math), but you get the point. Sure I can hit 1 fairway out of 1 try and I'll be hitting 100%, but I might not another one for a month.
Your comments made me laugh, thank you. It's a fair question you raised. Back in those days when I was a lot younger where I played basketball
3-5 times a week, I could regularly hit 70-75% FT. When I played sporadically, meaning about
2-3 times per month usually on Saturday afternoons (my condo is only 70 yards from an indoor basketball gym), I could manage at least 50% on, say, 100 attempts. So however you slice the math, I could make at least 50%. You don't have to teach college-level statistics and calculus to figure that. In mathematical statistics, there is a basic principle known as the law of large numbers - AKA the law of averages as we laymen call it in our lexicon.
I think the main problem with many college players in regards to foul shooting is in their confidence and coolness under fire. In the gym where players are free of all kinds of on-game pressure, they do pretty well with the FT, usually getting it above their on-game actual average. The glare of the lights, the taunting from fans, the manifold pressures of the game, the tiredness, the critical nature of the closing seconds at the foul line all put the player on the difficult hot spot which affects their concentration and only the mentally strong can deliver well and approximate their gym performance. I vividly remember how Ryan Boatright coolly sank three straight free throws at the closing seconds of that game against FSU in the Paradise Jam 2 years ago to put the game into OT - a game which the Huskies eventually won. Three straight ones from a mere freshman!!! I wonder if studies had been made comparing foul shooting in gym vs on game . Also, I remember Allen Iverson who never practiced but was always exceptionally great at FT shooting and whatever else he shot on. Juxtapose that with our Ray Allen who practices ever so intensely many, many minutes before
every a real game. Either one is considered superb shooter - FT and what not.
In golf, I believe the closest parallel of end-game foul shooting where mental strength/focus is a huge factor is the
putting - not so much the ball striking and distance to the fairways and farther up, although that is a big part of the golfer's arsenal of tools, too. For example, Tiger Woods did not three-put at all in his most recent victory. I believe he made only 2-3 bogeys in over 72 holes. I believe he was only ranked 4th in terms of putting the ball in the fairways (am not sure about these figures, btw, just vaguely recollecting them to drive a point).
