There are plenty of teenagers who can throw a rock that far. Not a particularly difficult "legend" to credit.

That is a football field in length. Nobody can throw a rock that far. Major leage outfielders can't throw a basenball that far.

Correct.

Nobody can throw a rock that far.

Incorrect - depends on the size of the rock.

Major leage outfielders can't throw a baseball that far.

Not with any accuracy - but guys like Don Grate have thrown baseballs well over 400 feet.

98 and 99 yard passes have been completed in the NFL and incomplete passes that far have been thrown many times in NFL and college play.

Shotputters can throw a 16 lb metal ball 60 feet and further.

Golf balls, which weigh an ounce and a half, have been thrown over 400 feet as well.

In 1989 I watched a game where Bo Jackson threw out a runner at home with a throw of well over 300 feet from deep left center.

Not only was it an amazingly long throw, it was dead on accurate.
