The Pop-AJ connection at that point in time was undeniably close. Pop had been on the Spurs' staff in 1990-91 and 1991-92 when Avery got his first two chances with the Spurs. While Pop was an assistant in Golden State, in 1993-94, Avery made his real breakthrough as a player, and when Pop became GM of the Spurs in the summer of 1994, his first two moves were the trade to reacquire Sean Elliott and the signing of Avery Johnson. There was a lot of speculation during the summer of 1994, when the Spurs were looking to replace a coach and a GM, that Popovich was the preference for both positions, but he apparently thought it best to take only one and wanted the GM position; regardless there was significant sentiment in that time frame to give Pop the coaching job, so his coming to the bench was always a possibility (and may have even been what Spurs management and players desired).
Put all those pieces together and you could see that AJ is a likely candidate to lobby hard for Pop to be the head coach.
My recollection is that Sean Elliott was also part of the group of players that wanted Pop to replace Hill, but I might just be misremembering that.
