I read something a long time ago from when Raymond Berry was coach of the Patriots. He was demonstrating a route to receivers, and he kept going out-of-bounds on the practice field. Feeling something was wrong, he had them measure the field, only to find it was something like 1 foot two narrow. Talk about obsessed! Maybe this is why our undrafted receivers seem so productive, while our "top paid" receivers are not producing. Interesting article.
