I have always found cricket coaches to be passengers with the team, enjoying the tours and locker room views of the games. I can get with a good and proper head coach, to be sort of a general mentor and supervisor, and maybe a fielding coach who can run drills and fitness sessions. But a bowling coach and a batting coach in cricket are useless positions. There's only so much advice and tips that a coach can provide to every single player, as everyone is different to how they were as a player. For example, Mo Yousuf can maybe provide Babar tips on staying on the crease for long and picking length and stroke-making, but how on earth would he advise him on activating his power game? What can he coach people like Asif Ali on? And if one makes the argument that a batting coach can help with technique, then I don't recall batsman, at least Pakistani, that has magically changed their technique during someone's coaching tenure. Mo Yousof as a coach especially just seems to be hanging around.
Don't even get me started on how useless a bowling coach is. What would an average fast-bowler, for example, coach a spinner? Just one of many faults.
I think consultant roles can be handy at times -- someone who is intelligent and can read and analyze the game and provide their input and motivation to the team. Mathew Hayden I feel was effective in whatever he did. But hiring random retired players as coaches for a team like Pakistan especially where is so much politics and inside resentment for one another, is pointless. Someone can be ripping apart a player and the whole team on TV one day and if offered a coaching role the next day would take it without any thought and then go and act super friendly with the same player that they were exhibiting personal dislike for just the day before.
To conclude, think back to any batting or bowling coach in the last decade and name me one that actually particularly benefitted Pakistani batsmen/bowlers in any way. As someone here mentioned, cricket is just a game where you work really hard and improve with your own drive and efforts -- and a supervisor/mentor could be helpful, in my opinion. I'm sure the players would know as well that no coach actually brings much to the table.
