Has Toub ever drafted special teams players highly? I was under the impression he took the players he was given and molded them into a unit rather than actually picking the players, but maybe that's just me.
I doubt Toub was even consulted on draft picks, and if he was, it wouldn't be until later rounds on players he identified as possible contributors.
Unfortunately, Belichick isn't walking through the door, and the Phins are going to have to choose between the candidates available, and since all are going to be unknowns for various reasons, Miami is going to have to choose the one right for them for their own reasons.
As for the hiring process, and hiring players he knows, of course he does that. I'm a hiring manager, and I hire the best person and best fit for my open positions, but when I'm hiring a new manager, I'm going to hire the person I have the best feel for. It doesn't mean it has to be a person I knew previously, but it sure gives them a nice head start. I know them already. I know what they're about. I'm comfortable with them.
That can be overcome by a great interview, but unknowns start out behind.
