As we know, Coach Haley has recently filled two important positions, OC and DC, with prominent candidates. 

In the case of DC it was very apparent a year ago that Crennel was the primary candidate and that the position was eventually, and very hesitantly, filled by someone already on the staff.  After one year, that Caretaker (Pendergast) was ousted for the originally preferred candidate, Crennel, because he finally became available.  It is widely suspected by us all that this move was almost entirely planned by Pioli/Haley the whole time.

The case of the OC is a bit more convoluted.  Gailey was apparently the man, until he wasn't.  The position was, perhaps hesitantly and less than ideally, filled by someone already on the staff, Haley.  After one year, the Caretaker (Haley) was ousted for a well connected candidate (Weis) because he became available.  A move here was almost certainly going to be made anyway because Haley has stated since he arrived that splitting the HC and OC was his preferred setup.  But, I wonder how much of this move was somewhat pre-planned and discussed by Pioli/Haley and Weis the whole time.  I think Weis was widely considered to be on the hot seat and this trio may have made pre-arrangements for that eventuality.

That finally brings me to speculate on Part 3.  There is another position that was very likely filled by a Caretaker this season with a preplanned successor to be acquired later.  That position is QB Coach and was also filled by none other than our beloved Coach Haley.  Lo and behold, we have now learned that his friend whom we know he stays in frequent contact with, Kurt Warner, is going to retire.  Warner's retirement could not have been a secret from Haley and it seems likely that these two could have been having discussions around this topic all season.  So, I suspect that by this time next week QB Coach Haley will be fired by HC Haley and replaced by new QB Coach of the Kansas City Chiefs, Kurt Warner.

This all explains why Haley has always said it would take 2 years to build his staff.  I love this move.
