the coach in football has responsibility for in-game tactics, in cricket they don't. once the game starts, that's it. you don't decide the bowling changes, set the fields etc. that's the captain's job.
essentially, what in football is generally the responsibility of the manager (player development (including appointing coaches), general strategy, and in-game tactical switches) is in cricket split between a coach and captain. therefore any captain mode or coach mode or manager mode in cricket means you either give the captain or coach responsibility that they don't really have, or you would have to massively restrict the options available to the player.
i am not saying that you can't fudge a playable, even enjoyable outcome, i am saying that outcome is divorced from reality.
The outcome is divorced from reality in football management games too. Very few clubs actually just let managers go about their business in negotiating contract, and whilst such things are simulated to an extent, there are clubs now that have different people for transfers and contracts than actually coaching the first team. If they can still merge such roles in football management games, then why not allow the player to be the panel of selections (or as the country does), the coach and the captain. In FIFA you can be the coach, the players on the park and such, and in the game now you can play as the whole team. No need to play the "divorced from reality card" when it's done that way across the board.
A management mode, similar to Cricket Coach, with squad selections, bringing players through and such would not only be fun, but is no more ridiculous than any other sports management game in terms of its connections to reality.
The best thing about it is that in terms of actually making such a mode, the gearing is largely something that is in itself fleshing out career mode as it is to be better. It's nothing taking anything away, but fleshing out player development, generated players, team changes, squad selections, AI selection, international rankings and all the like, you are also fixing the most glaring issues with the current manager mode, they can most certainly go hand in hand.
