Who suggested that? King doesn't need to know anything about James.
Personally, I don't think the two are connected at all- James commited to IU, King is (likely) committing to PU, both teams are getting good backs.
But people here seem to think they are connected and IF you believe that is the case, it's much more plausible that PU was holding open a spot for James then moved on to King when James went to IU, than it is that King told PU he was committing, PU calls up James who is already committed to OSU to tell him their offer is no longer valid (?), and that phone call somehow triggers James to decommit from OSU and flip to IU (which is also being the result of him getting pushed out of the OSU class as SDBoiler keeps telling us with absolute zero evidence).
