Kuminga or Reaves?

Ten team league, so the wire usually has a few diamonds. Most tantalizing out there now is Kuminga...

Is it time to hop on the Kuminga train? I rostered him recently until a few guys got healthy and now he's out there on the wire available to grab. My worst guys are Divincenzo (en fuego) and Reaves (kinda mid?). Should I expect Reaves to get a boost from a waiver deal (or perhaps just get hot again), and so hold him and pass on JK? Or should I jump on the Kuminga bandwagon and pick him up? 

Thanks!
