You wouldn't believe it, but it's all true. The field is 110 yards long and 65 yards wide. The endzones are deeep. You can run an entire route in the endzone. The players are much smaller because of the need for mobility around the larger field. Would recommend.

American football used to have the goal posts on the goal line. They were moved not because players were running into them but because they interfered with forward passing into the end zone. Rugby still has the goal posts on the goal line but they don’t have forward passing so it’s not surprising they haven’t moved them.
