You keep bringing up Granato’s statement and KA’’s statement about building from within. You shouldn’t put such absolute trust into their public statements.
KA has obviously tried to make moves that run counter to that. In addition, they just drafted 22 guys in the last two years alone. They won’t keep everyone.
Finally, they know they owe it to the players to continually try to get better. I am 100% convinced that they are still trying to add and simple math says that if someone comes, someone has to leave.
