I realized this morning that I know where Pronk's MoJo, or Pronkness if you will, currently resides.  He has clearly loaned it to LeBron for the Cavs playoff run.  Pronk's slump seems to coincide with the Cavs beginning their second round series with the Nets and has continued pretty much through May.

With May closing however, an unexpected thing has happened.  Because of the Pronk's great sacrifice, his MoJo and LeBron's have been combined now and each has MoJo equal to the sum of the whole.  Hence in the last two games Pronk has been, mostly Pronk again, but he's still learning to handle the doubled MoJo.  LeBron has had an easier adjustment to the doubling of his MoJo, since he's been carrying around Pronk's Pronkness, in addition to his inherent MoJo, for the last month.

Problem solved.
