This is an interesting one because the franchises have a very rich history against each other, but the overwhelming majority of ES wasn't even alive when most of the meetings took place.
The following records exclude the years prior to the Redskins moving to DC.
--Redskins lead all time series 37-28-3
--Redskins won the first meeting 34-24 in Oct of 1937
--Redskins have longest win streak at 12 games (1938-1945)
--From 1937 through 1969 the teams met at least once a season every year except for 1943
--The Steelers moved to the AFC as part of the merger in 1970 and the teams have only met 9 times since
--If you are counting that's 59 meetings in the first 32 years and 9 meetings in the next 41 years
--The Redskins are 3-6 in those 9 meetings since 1970
--The 70's era Steelers beat them twice (1973, 1979) with both meetings coming in Pittsburgh. The Gibbs I era teams then went 3-0 vs the Steelers, but we haven't won since; losing the last four meetings
--Teams have only played twice in Washington over the past 40+ years (1988, 2008)
--In those 4 losses, the Redskins HIGHEST point total was 13... They have failed to hit double digits in any of the past three meetings
--I generally have at least a vague recollection of every game played since the mid 80's, but for some reason I have no recall of the 1985 or 1988 games.... The one in 1988 is especially odd because I was pretty locked in by then. But I literally have nothing in the mental vault there. Both were high scoring games and both were wins, but I don't remember any of it.
--1991 at Three Rivers.... Remember this one vividly. My parents went to Rio De Jenerio that fall and asked if I wanted to go... I would have missed several days of school, but I also would have missed two Redskins games, so I decline and stayed home with neighbors. I stayed at my friend's house, but went home several times per day to watch the dog. I watched the Steelers game that day in my gameroom in an empty house which I thought was pretty cool. We rolled Pitt that day like we did many lesser teams in 91. Monk had a big day and the game was over early. Pretty sure this was Chuck Noll's final season.
--1997... The first of what would become many frustrating losses in 1997... We were 1-0 after a good opening week win at Carolina... We really outplayed the Steelers on the road that day, but Gus kept throwing picks... We still held a late lead before The Bus scored a TD to put Pitt ahead 14-13. I know Gus threw a pick in the end zone that day but I can't remember if he did so in the 4th or not. Anyway, it was a one point loss that easily could have been a 10 point win. Another Norv era game where our opponent to waited around for us to implode.
--2000: We blew the season already in previous weeks, so this game (played on a Sat afternoon) had no meaning for us. My wife (fiancé at the time) graduate from college that day and I only saw bits and pieces of this one. All I remember is that we got stomped.
--2004: Vague memories... Watched it from a sports bar in Houston. This was the year where our D was stellar but we couldn't score at all; this game for that mold. Pretty close on the scoreboard much of the game, but we never had a chance. Sean Taylor had a memorable hit on the sideline- was it Willie Parker? An ugly 16-7 loss.
--2008: Many fans were skeptical of our 6-2 start that year and this game validated those thoughts. We got off to a solid start, but Pitt just clobbered us after the first quarter. Big Ben started moving the ball and then once he got hurt, Byron Leftwich did just fine. Kinda knew our season might in trouble after this one. This Monday Nighter is of course also remembered also the "Steeler fan invasion" game.
