User blog:T-Drag/Kuma's DF is cheap?

Ok, so we all know that Kuma's devil fruit powers allow him to reflect everything. This includes rocks, swords, clothes, people, and even things like pain. Kuma has shown us that he is able to send people far away after some time.

So, my question to you is, do you think Kuma can send people underwater? i.e. can he send people with devil fruit powers into a river, and let them drown and die? If he can, then he's AWESOME. If he can't, he's still AWESOME. You're thoughts?
