He has a crop body, so 200mm should be ok.

Yes, ofcourse. I did take that into account. In my experience at the distances covered in (American) football stadiums, it is difficult to get full frame shots of players with a 200mm lens on a crop body, especially half way up the stand.

Assuming a player is an average of 50m away from the camera (which is a very conservative estimate), in order for the player to fill the frame of an aps-c sensor you will need a 600mm lens, and that's abslute focal length, not 35mm equiv. With a 200mm lens the player's body will only fill about 1/3 of the frame.

I made the above calculations using this focal length calculator.

You can ofcourse crop each shot in post processing but it's time consuming and you'd be throwing away 2/3 of your sensor's resolution.

So, my recommendation is to go for the longest lens you can afford, preferably something around 300-400mm if you want to get the kind of close-ups you see on the papers. It will also open up the possiblity of even tighter half body crops or headshots that can't be achieved with a 200mm lens.
