I think if they intended for her to replace Ken Daniels they'd be working her into that role already to get experience. The only game she really calls is the Red vs. White game, that I know of. I really don't get what their direction is with her.
I honestly think she's better suited to either take Keats' role, or, when Keats was off the other night, Trevor was at the desk and Natalie was doing Trevor's gig. Have Trevor run the desk and put Daniella in Trevor's position. She comes off as way more knowledgeable and professional than Natalie.
To me, it's a "Use her or lose her" kinda thing. She checks all the boxes for what you look for in a female broadcaster. Philly had the same with Taryn Hatcher and ESPN/TNT weren't smart enough to jump on her. (To be fair they probably couldn't because she worked for Comcast) Now she covers the Eagles and it wouldn't surprise me if she's doing National NFL broadcasts in the next couple years.
