First SB win in 86. Not a "classic" game but after watching the Giants through some pretty horrible years in the 60's and 70's it was a great feeling.
SB 42. I had a party at my house for the Green Bay game and when they won, I was jumping around with my football helmet on yelling that I was going to the SB. Not the Giants going, but I was going to the SB. My father and I agreed that when the Giants made it back to the big game, we would go together but unfortunately he died of cancer in 2006. I bought a ticket before even thinking about who I would go with and share the experience with so I bought a single ticket on the 40 in the 30th row.
I ended up going to the SB with a friend (pats fan) but we didn't sit together. When I got to my seat I found out I was sitting right next to Dave Diehl's mom, wife and brother! Dave's dad died the year before as well so it was emotional for all of us. Right before the big play I said a prayer to my dad and the very next play was Tyree...I literally cried!
The rest is history. When the game ended, I went down on the field with the Diehl family and Dave signed my Jersey. Greatest sports experience in my life.
SB 42. I loved SB 21 because it was a great win after suffering through the 60s and 70s drought. But, it still didn't leave the emotions of the win of SB 42. When I watch that game any time with Eli pulling away from that mauling group, throwing the ball to Tyree, him, holding the ball against his helmet, draped with a defender and holding on to the ball. Then the ease of Plexico catching it. Plus those last 39 seconds that Brady can't make it happen. Tears come every time. And for a little icing on the cake, I live in New England.
Obv SB 42, but aside from that one...
1-The first game we played after 9/11. It was against KC. It was such an emotional game... KC's mayor came out onto the field, declared it "NY Giants day." The KC fans had banners saying "We <3 You NY", and for a good quarter or more, they were cheering for the Giants to win, not the Chiefs. And we did win, in a good game, and it felt so good. Just for a moment, nothing else mattered.
2-The 2012 reg season game against the Packers. I went to that game. It was after a few weeks of writers saying Eli had a "tired arm" and they started questioning him, and us. And left us for dead, basically. Eli got his 200th TD that day, shut Simms up. Every time Eli scored, the stadium played "I'm Back in the New York Groove" and it was awesome. And we destroyed them, which is always fun. :)
