Like a lot of people, I've seen the good and the bad from the McCabes and I still don't like the idea that they own the ground.
The recent moves do suggest the start of a serious shift towards EITHER the Prince and his people taking over completely, OR the strengthening of the management structure with a view to engineering a sale to the Chinese.
McCabe delivered us from a very dark period in the club's ownership (Woolhouse, McDonald, Hashimi etc), delivered a stadium to be proud of, and has finally got us back to the minimum level that a club like "ours" belongs.
I think he's lined his pockets from time to time and been less than honest on some occasions. He was also a Board member at the time of Black Thursday.
However, all things considered I fall off the fence on the positive side. I'd rather have McCabe than Chansiri, or Venkys, or Tan, or Shinawatra etc.
Summing up, "better the devil you know", and if this move is the start of KM and his family moving out the door (he'll probably be made Honorary President or similar anyway I guess) I'd thank him for his efforts, wish him well, and start shitting myself about who might take over.
