Chris, I've read several of your interviews over the past year or so, and it seems like this has been a good experience.
I'd still say today what I said back then...follow-up questions would be so helpful to get you to move away from the script. From what you've said in the past, you're on a strict time limit and want to get all of your questions in. If you're going to ask about who he would like to interview, why not a follow-up question about why George Clooney over anyone else? For instance, it might be fair to assume that he has had some interactions with Clooney in the past, and maybe can give some insight into why the guy would be interesting to bring on the show. Even if he hasn't met him, it might be good to know what impression he has of Clooney that would make him think he'd be a good fit on the show. Just something to help the transition, because it launches right into the more serious topic of the NFL coverage that's out there.
I thought the follow-up question you asked to start the interview was really effective. He gave you a boilerplate answer to your question about his book, but when you asked about what else he wanted to accomplish, he talked about all the preparation that goes into his work and giving readers some access to that.
But, again, I would've loved to hear his reaction to a follow-up about the NFLN not being aired across some cable providers and whether he felt the NFLN bore any responsibility for this. He framed it as all of Time Warner's and Comcast's fault. But, there are some who would argue that the NFLN is to blame. I'd like to hear how he would address that.
You've been persistent at doing this, and you've had the chance to interview quite a number of folks, it seems. I still think the best insights come from when you can be spontaneous in keying in on what the guy is telling you and nudging the interviewee into a direction to be more spontaneous, himself. You ask very good questions that address a range of serious-to-fun content. But, I do find myself looking for more continuity throughout the interview, rather than the feel I get that there's a script, and that takes the higher priority.
Just my .02.
