Like I said, very valid concern. But I guess what my thinking is that it is also possible that last year was an outlier for them. Sencire and Ty took 20 and 31 total free throw attempts, respectively, all last year. I don't know at what number of attempts it takes for FT% to stabilize, but I imagine that 20 and 31 FTA are considered a relatively small sample size.So what is a realistic expectation? If they doubled thier percentage from last season for each of them they would still struggle. That is just very unlikely. If they shoot improved to the mid 50s that would be a major improvement but still will keep them on the bench down the stretch.
That's why I was wondering what their FT% was like in high school. If they struggled in high school as well, then for sure, they are probably unlikely to improve enough overnight, but if they were good free throw shooters in high school, then I'd say there is a non-zero chance that last year was just small sample size weirdness. Not saying it is, just saying it's a possibility.
So it's certainly something to be concerned about, and to keep an eye on, I'm just of the opinion that it isn't necessarily a foregone conclusion.
