I totally agree about the refs, especially seeing the Pats* benefit from referees subjective calls (PI, Holding, etc.) But as I mentioned to a poster last night, hopefully, the helmet rule will alter how players tackle; whereas, the catch rule is absolutely related to referee perception (subjectivity). In other words, the catching situation does not involve altering how players play and is at the discretion of officials. The aim of the helmet rule is to alter how players play. Let's see how it develops.
