I'm assuming Angels Tsai is available?
Kayte would be great and you would presume a lock for the show. Talented, knowledgeable, funny, good on TV and attractive. And people like here.
I can't see Dave as the TV host. It's a particular skill set to move quickly in and out of recorded stuff and set up Kayte. That's not Dave's radio shows. Maybe he's got those skill, but no TV reps doing it. While it shouldn't matter, looks matter in TV to casual fans.
J Ross or other KHTK talent like Deuce make some sense, but the question is how natural can they appear on TV. If they can't pass those screen tests, might be a deal breaker.
I wouldn't be shocked if the primary host had other duties with Comcast BA (more duties in the Bay Area in the off-season). Decent job and particular skill set set so it could be new blood from outside the market. That will probably turn on who owns the show. The Maloofs owned the broadcast and sold the games to Comcast. As such, they had total control over talent and loaded up with KHTK folks. If Comcast bought the rights to produce, I'm sure the Kings will have a ton of input but the host staffing of this show might factor into the broader staffing decisions of Comcast BA.
