For me - the "turn" for that team was when Dennis Tueart left. We were pretty poor for the whole period from end of winter 1977-1978 right through to the summer clear out of 1979 under Big Mal - so for me the thing to note is that even with the "Book players" we were doing as badly as we did with the "Mal players" the following year. In particular - we went months without a win (or was it home win?) under Book in 1978/1979 and seemingly had lost the ability to defend and also to score goals at home. Perhaps then - the previous couple of seasons had been a flash in the pan, what with the young unknown Barnes coming into prominence, and we had been sussed by 1978? If you look at any of the You Tube footage from 1978/1979 even before Mal came back- City look absolutely clueless.
If we had kept Bookie and Bill Taylor - this is the kind of surgery (with benefit of hindsight, big style!) which might have kept us moving forward:
Joe Corrigan - keep
Kenny Clements - flog (not v good), probably Ray Ranson was about as good a young RB as was around at the time so give him a go
Dave Watson - keep longer and pay him wages needed to keep him from abroad
Terry Butcher - offer Ipswich £750k for their young defender instead of buying Robinson for that price
Willie Donachie - flog as past his best; buy Kenny Sansom from Palace for £1 million
Peter Barnes - flog for 750k as too one dimensional - buy someone like Arnold Muhren for 500k
Asa Hartford - keep
Garry Owen - flog for 400k and buy Bryan Robson for 1 million
Paul Power - keep
Strikers - all flog
Buy Rush £300k
Buy Peter Withe for £200k
