Monday Night Football

It might be just me, but I wonder: is there still a real person hidden (deep) within John Madden?

Or has he now become nothing more than a combination of tics and meaningless phrases and "booms"?

He reminds me of a poorly written character in a would-be noir novel -- all eccentricity with no reality. I could comment that he could use some fleshing out, but when I think about seeing him in the camera shots within the booth, perhaps he's plenty fleshed out already.
