If the information in Post #140 is correct, then the officials blew the call.
Of course, I've been saying for the last two weeks that this Giants team didn't even belong in the playoffs. So I've got nothing to complain about. They didn't deserve to win that game because they didn't make a single "winning" play all game.
Per
this link, Saubert was eligible and did report in as such. Pass interference should have been called on the 49ers, but was not. However, #65 of the Giants, Hopkins, was ineligible.
