Both Rizzs and Rathbun were in a no win situation in Detroit. Following a legend who got tossed the way Ernie did at the time.
They both ended up on their feet in a more amicable situation. Rizz, back to Seattle. Bob ended up in Atlanta (much closer to home and both he and his wife's family)
Rathbun has had a good career doing college football and basketball. As well as being the Hawks lead announcer for several years. He also did Braves play by play for a while.
In many ways, especially for sports media, Detroit fans have a bit of "small town" views when it comes to announcers. It's the "you're not from around here so your not one of us" attitude
