I never played football and have a question for those that have...How much is retained within the team culture when you lose a high grade assistant? Say we lost Ash, wouldn't we (Urban), within the 2 years Ash coached here, have learned how he taught, what he taught, ...and wouldn't Urban keep what he liked & learned and be able to impart that to the replacement? I'm not discounting charisma, personality, "I'd run through a brick wall for him"... What specifically is lost -in football terms (not recruiting)? Thanks in advance for your input.
