Mike Williams never demonstrated possession. The ball was moving before he dropped it out of bounds. That is not even a close play. Please look at it again! Bad calls do happen, but most of the ones you are mentioning were the right calls.
The rule was posted in that other thread which you apparently still don't understand. It is hilarious that you are arguing that the Mike Williams play was a catch (when he never demonstrated possession and he completely dropped the ball out of bounds) and arguing that the Manningham play was not a catch becasue the ball moved slightly. Just like you argue that the Cruz play was a bad call when they ruled him down, but argue the opposite on the Holmes play.
It's alright. It is all just one big conspiracy against the Jets.
