Even the morons out there knew that Rodgers wasn't retiring from the NFL this season LOL!
While we may never know "the truth" about the entire process, I feel that Sony picked the best people based on a lot of things. From one's age to one's availability, as mentioned, it probably wasn't a difficult decision. IMO, I don't think Sony cares about offending anyone when it comes to race and gender. I'm not saying that they're prejudice at all; I'm saying that they're goal here is the choose the best candidate (for the long haul), regardless of race and/or gender. Based on the criteria, I really think that Jennings, Richards, and Bialik were the most qualified out of everyone else.
As mentioned, I can't crush TPTB for their call, nor can I give them a standing ovation. As time passed over the week since the decision was made, I think Sony got it right. Well, Ken as the successor may have been "more correct" than not, IMO. However, I would've compared that to a most popular high school junior slated to become the class president in his or her senior year only to get upset by someone less popular (with a VP or Sec/Treas consolation prize instead). IMO, too obvious of a selection for Ken Jennings as Alex's successor.
Outside of the stuff that occurred at the beginning of the previous decade, Mike doesn't really have a big history. It helps that a lot of people have never heard of the guy. Plus since the nonsense that happened, he's pretty much moved into a positive direction, both from hosting and producing. With Mayim, having her as the exclusive host for (primetime) specials is fair enough. It's sorta like Baldwin, Strahan, and Banks hosting primetime gameshows that are seasonal but not year-round. All of them are busy doing a ton of other stuff. Sure Mike Richards could've hosted the specials, but as mentioned, he's relatively unknown, sorta boring, and really business like. In time, he could host those; after several years of hosting Jeopardy, he'll feel more at ease. At the end of the day, several people watch for the game itself & every-so-often, a super champ
