3. 1992 NFC Champoinship game against the Cowboys. From the NFL hiring a grounds crew to fix the field, to the phantom holding call on a Jerry Rice TD, and the "how bout them Cowboys" crap! That game literally made me sick to my stomach.
2. 1983 NFC Championship. Till this day I've never seen such a big game so horribly officiated. There was bad call after bad call in that game it was disgusting. And to see a great Montana comeback thrown away by the officials was too much to handle.
3. 1991 NFC Championship against the NY Giants. This loss still gets me down. House full of people ready to storm the streets of S.F. and........FUMBLE!!!!!!
I never cried over a game until this day.
