If I was a Detroit Lions fan, I'd be screaming for referee blood about that.Picking up that flag on a FLAGRANT pass interference by Dallas in the fourth quarter was the worse call... or non-call... the NFL has seen since... well... since the non-call on the botched field goal attempt in the Giants/ 49ers playoff game ages ago.Shocking. Really shocking.The Lions could still have won the game. They did lots to blow it afterward, from penalties of their own (none as flagrant, none picked up) to blown coverages to a shanked punt and a fumble. But still... Detroit could well have locked up the victory on that drive, the play was textbook pass interference, the penalty needed to stand. The defender mugged the tight end.One for the books.
