It's the least important and completely non-scandalous mystery of the club's beginning, but it bugs me. Why did they even do it? Why make this show of him being STH #1 and then never follow through with even a single additional event or appearance? I am pretty sure that his name was on the special edition "First 3,000" 2015 season scarves, but he never made one other appearance with the club or at any games.
My best guess is he expressed interest in 2013-14, they offered him 1st STH status as a mutual courtesy, he accepted, and then 2015 comes and he asked for money to use his name and image and the club said no. But that's no more than a guess.
