I don't think it's just WRs asking for clarification. I think it is everybody that has anything thing to with football and anyone that has an interest in it. There is no consistency with it. One play the receiver gets his hands on it but drops it before getting any type of control or taking a step or making a move and it's called a fumble but a couple drives later receiver catches the ball, tucks it so ball is secure, takes 4-5 steps, gets hit and goes to the ground with possession then rolls over and as he's getting up the corner hits the ball out of his hands. No catch.
I don't know if it's more of the referees are incompetent or the rules are that messed up but every referee crew is very inconsistent in what they call complete or incomplete. They had Mike Carey on during a review and he said that clearly wasn't a catch here's why____. The red came back and said it WAS a catch and here is why _____. Then the announcer went on and on about how the referees don't even know what is a catch.
