Photojournalism and sports are fundamentally different things. Photojournalistic photographs often need to show CONTEXT, and many are shot with wide-angle lenses, or from vantage points that show some background, some setting. It always "depends" though; the exact, specific use of a photo determines whether a long, medium, close-up, or extreme close-up look will work to tell the story or not. Sports photos are another, different thing than hard news photos; the photographer has a LOT more advance notice, and can usually chose a number of vantage points. Often times, the viewers will already be INTIMATELY familiar with the subjects in sporting photos;Joe Montanna, Muhammed Ali, Joe Frazier, George Foreman, Wayne Gretzky, Peyton Manning, Tim Tebow---viewers have ALWAYS been able to recognize these types of athletes, instantly, and since they each specialize in a sport, there's not as much need for context if say, the photo is accompanying a news story about a SPECIFIC bout,match, or game. Many daily newspapers like tight,tight close-up 300,400,500,600mm action shots, with blown-out backgrounds that show a lot of "face" and show "expression", but which quite often lack contexual clues. Some of the most-famous sports photos show a LOT of background. And by that, I mean a LOT of background.
Here are some legendary sports photos. NOne of them are "tight" shots.

There is no need to crop ANY of these shots...cropping would only ruin them. Sure, the Ali-Liston shot CAN be cropped, and has been...but look at the Secretariat at Belmont shot...cropping out all that "useless background" would make the shot into a worthless kill-file shot. Same with the TIger Woods photo.
