I agree, many of the things that Illitch has done have benefited the city. He pursued projects which made him rich AND which tangentially helped the city. I never followed the logic that you have to show some sort of reverence to Illitch because he's done so much for Detroit, and by "done so much" we mean "built himself a casino". I'm glad he doesn't mind spending money on his sports teams, I love watching them win. But he's as susceptible to ribbing as anyone else and perhaps more so, when he does things like announce a new arena with all it's fanfare, buy up all the property around the new arena which will skyrocket in value after the arena is built, and then ask the public to pay for the arena. What a charitable soul!
While of course he's done things that benefitted him financially (he is a successful businessman after all), he's also made business decisions that benefitted Detroit when he could've gone elsewhere.
I wasn't saying the guy is a saint. My main point is I think it's a little childish to slander someone as senile and drunk, particularly on a website called "LetsGoWings" when he's a large part of the reason there's something to root for with the franchise.
