On Keepers, Hallworth, Rhodes & Grobbelaar were all 6 foot 1.
We also had a (crap) keeper by the name of Ian Ironside (1 game played, league cup 2nd leg away at Grimsby which we lost 5-0) who was 6 foot 2.
Pogs stood at 6 foot 5
As for John (or Jack) savage, he was a keeper but doesn't appear that he ever played for us. Clubs on Wikipedia are: Hull City, Halifax Town, Manchester City, Walsall and Wigan Athletic. No idea how tall he was though!
