I love this show, but the inconsistency with the timeline drives me crazy.
In the first episode, the Big Three were celebrating their 36th birthdays. Thus, when they showed the scenes when they were born, it must have been 1980, right? Well, in an EW interview, the creator said it was 1979. That would make the modern day scenes to be 2015, but okay.
Then, last week they were talking about the possibility of having kids during the Steelers - Rams Super Bowl, which took place on January 20th, 1980. Kate mentioned she was conceived during the Super Bowl, which would mean the Big Three would have been born in October, 1980. All right, maybe the creator just misspoke when saying it was 1979.
However, tonight when the showed Randall's report card, I believe it said he was born in June of 1981 (I erased it, so I can't go back and check). So that would make it a 17 month pregnancy and make the modern day 2017.
Also, they showed a flashback last week of Rebecca watching what appeared to be the 1969 Super Bowl with her family as maybe a ten year old child, but she would have been 18 years old in 1969 (in a 1980 scene, she said she was 29 years old).
Am I overthinking this? Yeah, I thought so.
