If you found yourself confused by Thursday's trailer for Avengers: Endgame, Richard Sherman is here to get you caught up.
Philadelphia Eagles defensive end Chris Long tweeted after the trailer's release that he was looking for a quick catch-up on the Marvel Cinematic Universe (MCU, for short). Who could blame him? Endgame is the 22nd film (yes, you read that right) in the MCU, and basically is the culmination of a story that began with 2008's Iron Man.
That's a lot of context to catch up on before Endgame is released on April 26, but the 49ers cornerback has a solution: Film study, and lots of it.
