Agree with some of what you're saying lorna but do think you've been a little harsh on Cookie.
Yes, like any manager to be fair, Cookie got in some duds but there weren't too many. Admittedly some of his favourites followed him when they should't have but he achieved the goal and most have stayed as part of Jackett's squad, so they cannot be that bad.
I'd also say, in fairness to Cookie, at times he DID need to bring in large numbers as the squad was consistently changing from year-to-year. Again, admittedly, sometimes down to his choosing.
BUT, great starts for those who have come in.
