Doubt Garrett is that cold but he is just being careful to ensure he and his wife will be monetary comfortable for rest of their life & he also ensures he gets the job he really wants (hopefully Cowboys and not Ravens). We will see what happens over the next 24 hours or so.
BTW: Garrett has been described by various people as relating well to people, very smart, etc. I do remember a scene on the sidelines many weeks ago when Romo and Garrett were standing around talking and Garrett (with a big smile on his face) used his shoulder to shove Romo just a little and Romo (also with a really big smile on his face and obviously in a very joking manner) then using his right shoulder gave Garrett a much stronger shove really knocking him aside. It just struck me they appeared to have an excellent relationship which both very comfortable with. It was very late in the game and Cowboys had a huge lead; Romo might even have been out of the game by then.
I also read somewhere that occasionally in the offseason (don't know about during the regular season) that they 2 of them would meet at VR sometimes in the evening to throw the football around and talk about the offensive system, etc.
I've always had the hope that Garrett and Romo were close enough that Garrett really didn't want to leave the Cowboys. In fact Romo was once quoted in the newspaper as saying Garrett would obviously get coaching opportunities elsewhere but that he (Romo) intended to have a say in whether Garrett would leave.
Realize this could all be wishful thinking if Garrett wants to become a HC now and doesn't care what kind of offensive personnel now on board with the Ravens, etc. Also if it turns out Garrett is set on the Ravens and it turns out he wants bring Cameron on board as their OC, hope Jerry Jones goes after Cameron in a big way.
