at the end of the day, missed calls happen in every sport. If you expect perfection stick to video games. Yeah, it sucks, and everyone gets irate at times, understandably so...been there many times myself...but it is what it is.
Look at the "catch" late in the game that went the Lions way, resulting in a 2nd and long catch, leading to a TD. It was not a catch, clearly, BUT they simply had a tough break with the "catch" call. I can not fault the refs call on the play...the ref right there could not see the ball at all because it was shielded by the body of the receiver, and called upon another ref to pass judgement. The 2nd ref was like 35 yards down field, looking straight on at the ball...tough to see a bounce with no angle. I was happy to see them get together on it, even if they did get it wrong. Bad/missed calls happen, and that is not changing...ever.
None of there refs want to miss a call or get it wrong, but they are only human. If you say you have never mad an error at work or in school or in whatever it is you do, you are only fooling yourself. Get you butt out there and volunteer to ref a minor league of some sort, then chirp how bad they are.
