Often times, I look at hosts and wonder if they're the best possible fit for that kind of show, and I find myself playing armchair executive, thinking they'd be a better fit on another show.
So, in that spirit, name any recent host (let's say anyone who's hosted in the past five years) who you think isn't/wasn't a great fit for the show they helm/helmed, along with a show currently on air you'd move them to if you had the power.
There's a few out there for me, but I'd move Kimmel off Millionaire. Even with a crowd, I don't see Kimmel ramping up tension or excitement as the players ascend the money ladder. But I think he would be perfect on Match Game. He's comfortable with celebs, there isn't a ton of game to keep track of, and he's good at ribbing people without being mean about it.
