It was all over the league on Sunday. If you see a receiver running into the flat all alone, chances are the defender covering him was picked by a crossing route or a slant. I don't recall seeing any flags on Sunday across the league, and it's very rare that the defense will get this call.
So how is this allowed to continue? How is it that this obviously illegal play is allowed to go unchecked? The rules are more than set up for the offense to have an advantage- they don't need unpenalized illegal pass plays too...
