I don't like this. People like Saqlain are workaholic and want to work. If he is given the job as a BCB coach, he might be under utilised, get fed up and eventually leave.
Also, the national team Head Coach is more than likely to refuse his offer as most coaches would see someone as famous, well liked person like Saqlain as a threat, annoyance, interfering and are highly unlikely to request his help.
I mean take Richard Pybus as an example, he didn't want Saqlain to conduct a spin camp. If he becomes the BCB coach are players will most likely be deprived of his guidance.
So either bring him as a National team coach, academy coach or don't bring him back at all.
Saqlain being praised by players also confirms one more thing and that is, while a lot of people say that famous players don't make good coaches, the opposite is also true.
