ShahZam talking about getting a coach on the Plat Chat podcast earlier this year
this info is from 9 months ago so who knows now, but SEN weren't looking for a coach to take the reins of the team and more of someone who would bring a different perspective to playstyle and help think of set plays and the like
at the end of the day, we'll never really know his exact role on SEN, but best of luck to them
