I think he has alot more influence than people think.
He was involved in transfers again this summer (ironically our window was poor compared to the one previously that Brands was doing alone)
He's still our Chairman and will no doubt be having words in Moshiri's ear regarding matters.
I also 100% believe he was the one who got Denise her job as CEO - No way Moshiri appoints her and not a Sascha type character from outside the club.
He was involved in transfers under Koeman, but it came out after Koeman was binned that BK would no longer be involved in that side of things, and he was going to take on a more of an ambassadorial role, just be the face of the club, ie, regale people with stories. I still stick by what I originally said, he's no more than just face in the crowd now.
