"these young guys don't even know how to rattle a cage these days."
The producers want to push a "rivalry" between Clint and Jeff now that they are in the booth together. Imagine Dale and Jeff in there together instead.
Also off topic and as BIG fan of both Dale Jr and Sr, while obviously everyone wonders how different Dale Jr's career would have been if Sr was around to help him, I have mostly always wondered what Dale would have thought of Jimmie and his championships, especially the 5 in a row.
