The thing is, the entire nation was looking, and everyone outside of some Packers fans, the refs and the NFL PR folks are saying that there was indeed nothing there.
Look, I'm not saying the Packers cheated. I'm not trying to take away from the fact that they took advantage of their opportunities. When they had the ball when it mattered, they did something with it. That being said, the entire nation watched the refs hand GB those additional opportunities on obviously bad (non)calls.
To be even clearer, kudos to GB for capitalizing on their chances. At bare minimum, there were 2 times that possession was given to GB via bad officiating (1st call on Flowers should have been a 4th down punt, non-DPI call on Redmond would have put Detroit in FG range). That is part of what drives me mad about the "FGs vs TDs" argument. The average NFL game is usually pretty close in score. The Lions had a lead, but had possessions (scoring attempts and time on the clock) taken away on bad officiating.
I'm not stating unequivocally that Detroit would have won had those calls been made properly, but the needle certainly remains tipped on their side.
