My opinion only, based upon past results / minor future projection.
3M is reportedly a knock down shooter. I expect that there will be some growing pains, but let's pencil him in around ~37% from three.
Tobiason only shot 34% from three last year, but shot 41% his freshman year. Can he get to around 36%? If so, he'd be a reasonable threat.
Doty hasn't shot well from three either year. This past year, he shot ~32%. He's a guy that can make them, but his shot seems like a bit of a set shot to me.
Anthony shot 25% from three. He can certainly make them, but shot selection was a big factor with his poor percentages.
White shot ~37% from three, in limited sample size. But I think it shows that he CAN make them, and can also be someone who eventually will be a reliable threat. The question is, will it manifest this year?
Dual shot 31% from three last year, the same as his sophomore year at Seton Hall. His frehsman year, he only shot 25% from three. I think he is what he is at this point -- he's a guy who CAN make them, but isn't a consistent threat.
So again... we have some guys who should be reasonable threats. Some guys who have shot reasonably well, and some guys who are shaky. Some might step up, but it is no sure thing.
I think we'll have some guys who can and will make some from deep. I just don't know if it is reasonable to expect guys like Tobiason / Doty to suddenly turn into [for example] 38% three point shooters. Will Kiyan improve? Will 3M light it up, or struggle as he acclimates? Will White continue to expand his perimeter skills, or was last year fool's gold?
Lots of question marks.
