Here's the thing with Bradley - the obvious answer seems to be that his jump shooting over the past month or so is unsustainable (the 66% from 3 obviously so, but you know what I mean) considering how poor he looked before. But he was such a highly regarded shooter coming out of high school and his form looks so good so.. who knows.
No, he's not going to sustain 66%, but his in-game jump shooting was poor when he was visibly nervous earlier in the year, but Doc's been talking about his shooting in practice and that's what he was known for as a youth coming up in basketball.
