I think you can. There's nothing that prevents the dorks of the world to understand and reason about a game. It might help having played, but I don't think it disqualifies you if you haven't. In general I hate arguments from authority, there's no single authority in basketball who will get absolutely everything right and every argument should be judged on its own merits.
The argument Locke makes in that podcast(that Kaminsky is the risky pick) is incredibly weak. He makes several huge leaps and distorts logic to reach that conclusion. Even to begin with - you need to know what one means when they say "risky" pick. To me risky pick in the context of the draft is one that entails a huge discrepancy between floor and ceiling, where the prospect is much closer to his floor right now and there is high chance of him not getting close to his ceiling. It also involves expectations. If you draft Frank expecting him to be a super-star that's a high risk pick, simply because the chance of that happening is close to 0. If you draft him expecting to be a great rotational player - then I don't think that's much of a risk at all. For me Frank is one of the lowest risk pick, simply because when you draft him you know what you are getting for the most part and you don't really expect him to ever become a star in the league(at least I don't).
At the same time - the question still stands - do we draft a most likely long-term backup player in the lottery? And is that a good strategy for drafting in the lottery in the situation we are in right now? I can see both sides, but if we get the chance to choose between Turner and Kaminsky, I know I wouldn't be choosing Kaminsky, simply because I can see Turner pushing Favors and Gobert down the road, while I can't really see Kaminsky doing it(I think if we draft him he's going to be our long-term 3d-4th big).
