Regarding Friedgen, I am pretty sure GT made an official inquiry to Ralph and he stated he was now happy at MD. My hazy memory says it was even part of the rational for him getting a pretty nice raise - good performance and concern as schools like GT came calling. I for one would have loved to have had him back on the flats. Beyond all of the hype about offensive genius I think he is just flat out a winner. I personally think it was this "winner mentality" we most missed last year.
Regarding Mac, as others have said about Chan I am sure he is a very good person. However, for every internal hire like Miami made (can't remember his name right now) there are more mistakes like Torbush (UNC) who are hired because they supposedly can keep the momentum going, have the recruiting contacts, etc.
Not to say Mac is a good or bad coach, but to think he is automatically or without a doubt the best choice because he was here and liked or did a good job at Seattle is equally as dangerous as always looking outside.
