Off the top of my head just some of the young and first time managers Hull City have given a chance too since 1970.
Terry Neill, first managerial job. Under achieved massively with a highly talented squad, John Kaye, first managerial job, did nothing. Ken Houghton first and only managerial job, did nothing, Mike Smith first managerial job ( of a league club) Bankrupt the club, Terry Dolan, recruited from Div 4 Rochdale, club appeared three times at the High Court on winding up orders, Eddie Gray, also from Rochdale, did nowt, Mark Hateley first managerial job, disaster...….Jan Molby very little managerial experience, did nothing, Phil Parkinson, did nothing, Slutsky did nothing, etc etc etc.
The only time we have hit the jackpot was when we have appointed an experienced manager, Phil Brown being the exception who had only coached before although under Sam Allardyce, Peter Taylor, Brian Little ( moderate success) Brian Horton, Nigel Pearson ( left a good squad and wasn't sacked) Steve Bruce...……
I'm sure others can add their own names to the list.
We were Horton's first job as he was player-manager. Brown had managed Derby before too.
