It's not hard to conceive of such a scenario, i.e. where there's nothing lost 
on the sides of the 4:3 HD capture. But it's very hard for me to believe that 
this high res 4:3 image would be acceptable to NTSC analog sets. In shooting 
soccer or football, the ball would disappear on analog sets.

So IN PRACTICE, my bet is that the videographer is zooming in to the ball 
*more* than he would be for HD displays. Resulting in less content on the sides 
than ideal for the HD monitors out there.

If people insist on using 4:3 HD capture, then the better choice would be to do 
both pan-scan and tilt-scan for the 4:3 SD extraction to analog sets. Failing 
that, the 16:9 becomes the more compromised output. That's my bet.
