I've been a fan since 75 so have seen many Thanksgiving games for us, but this one still remains my favorite.
1990. We had upset the Rams the previous Sunday and were playing a quality Washington team that would ultimately make the playoffs again. This was the 2nd win of the late season 4 game winning streak, and we nearly made the playoffs in Jimmy's 2nd yr. (I think we def would have had Aikman not gotten hurt early in the Philly game week 15)
Emmitt's rookie yr and his biggest game of the seaso with 132 yds on 23 carries and 2 tds.. Troy threw two picks but otherwise had a great game, throwing 1 TD to Irvin and standing in there under a pretty strong Washington pass rush all game. Emmitt sealed the win with his 48 yd TD run in the 4th qtr, breaking free from Darrell Green to get into the endzone. It was kind of the game where I felt like we had finally re-arrived to real relevance in the NFL. We'd beat New Orleans the following week and then destroyed the Cardinals (Emmitt scored 4 tds that day).
