Cobb Morley wrote the first set of rules for the Association. This was because at the time different clubs played by different rules. The game would start by teams agreeing what rules they would play by. Some games were played under the two goal rule, the first team to score two goals won.The unifying of the rules caused some separation between clubs and the result is still seen in the differences between Rugby League, Rugby Union and Association Football.
Hull was not the birthplace of the FA, simply the birth place of the man who wrote the first set of rules and who became the first president of the FA. Hull City has no connection with Cobb Morley and to link him with the team really is stretching history. Whilst I like the idea of celebrating his memory, it really has nothing to do with Hull City.
