GREEN BAY, Wis. (AP) – The temptation when playing a receiver as big, strong and scary good as Calvin Johnson is to get aggressive, try to outmuscle him and hope it throws him off his game.  Do that, and you may as well ask the Screen Actors Guild for membership because the highlights of Megatron’s mega-day will be all over TV for the rest of the week. Maybe the rest of the season.   Just ask Green Bay Packers cornerback Tramon Williams. He’s seen Johnson twice a year for the last four seasons, and it will be his responsibility to make sure the NFL’s leading receiver (in yardage) doesn’t have a record-setting day Sunday like he did the last time the Packers (6-3) and Detroit (4-5) played.
