I also liked him when he began, but dislike his schtick now. Not unlike Chris berman. Those old jokes and routines are just so worn. Do we really need to hear him call someone a PTPer again? And then have to tell us what the 'acronym' means? The bits are just stupid now. They were (almost) cute when they were original 25+ years ago. 25 years later, the same schtuff is just annoying earburrowing. Superficial, redundant gimmicks for the idiocracy. Like reality tv.
"He IS college basketball?" No. Games that he doesn't broadcast are no less interesting. But, saying all that doesn't diminish his early role in promoting the sport. He HAS done that. He has done a lot for charitable organizations. Critiquing his broadcasting isn't the same as critiquing the man. I'm not one for giving a guy a pass for being a nice guy if he's rubbish in his professional responsibilities.
A giant hole when he retires? That's overwrought. When he retires, we will barely notice. He may be the sport's biggest cheerleader, but he sport is bigger than a broadcaster. John Madden retired, and although I loved him, I missed him for half a season and then noticed the world was still spinning, and football was still great.
