Or something like what Bill Nye does. If Dave could expand his analysis a bit, I could see him having a very popular channel/show outside of the billiards world. Analyzing the physics of basketball one day, then baseball, maybe even topics outside of sports. He could give his informative, humorous, and (most importantly) functional view on many things, and fill the need after Neil. That is, Neil introduces people to a concept, and really is for raw beginners who are curious. Then Dave's focus can be on people who now want to understand more in-depth so they can use the material in practice.
Might be easier said than done, I'm sure, but if Dave were giving an analysis on how to best hit a jump shot, or even thoughts on how to best hang a light fixture, I'd certainly watch.
