Your OP which I responded to specifically stated the “risk of shooting <30% from 3”...that was where I disagreed with you, so I’m not hung up on a number, that was literally what you said and what I was replying to.
You didn’t say “the risk of coming back and his 3pt% not improving is not worth it”, had you that would be different. I agree in that in order to improve his stock that percentage likely needs to improve, as I don’t think he can make big enough strides in other areas, the most likely would seem to be FT and 3pt percentages.
I’m not sure what he will shoot, but I am very confident it won’t be under 30%, nor do I think there’s much “risk” of that happening.
