IDK, I guess I would have to see clips of FT's back-to-back, but his form looked really good to me. Of course it isnt 100% smooth, that's probably the nerves at play, but it's a smooth one motion release without a hitch.
He's already completely rehauled his form from the Kansas days, I dont think he needs to do it again. IT's probably more just getting comfortable with it in game.
Like this FT looks great to me. The form is pretty damn good. Maybe it's a bit rushed and could be slowed down, but it looks good. He just shoots it a bit too hard/flat and hits back iron. There might be like a few degrees he could improve on with his launch angle, but it's very very minor tweaks.
