A bad idea on so many levels. I'm saying this as a fellow writer who has TV experience on panels and being interviewed, etc. I would be a terrible anchor on PBS, much less an anchor on the most-watched sports show in the world.
Reilly's background is print writing. Sure, he could probably write OK television copy. But it's a whole other world to actually get in front of a camera and deliver it smoothly. It's freaking hard to do, and being in front of the cameras answering questions from a real anchor as an analyst or whatever doesn't prepare you.
I imagine there were only two people on Earth who thought this was a good idea. Rick Reilly and the higher-up that OK'd it.
