I'm not connected like others, but reading between the lines a little, dating back a few weeks or so, there were a couple ND guys saying the QB who comes to ND may not be among the publicized short list. Back then everyone was saying Card, Leary, Armstrong, Pratt.....maybe a few others. I could be wrong, but it would appear someone knew exactly where Rees was and had some insight that this might happen. Especially since everyone is already talking as if it's a done deal.
So as it pertains to not pressing for Card or Pratt, etc (bird in hand) while waiting on Hartman....my suspicion is that they already knew Hartman was coming and were just ironing out details and waiting on an announcement date that was suitable to both parties.
Just my guess.
