It is likely what happened during the Half Time show that will be talked about long after the game.
According to sources "the NFL nixed both Eminem's request to kneel in support of Colin Kaepernick and Dr. Dre's request to use his lyric "still not loving the police.""
The NFL didn't want Eminem taking a knee or to create any discourse with their audience. During a tribute to 2Pac, Eminem in fact did take a knee similar to the pose taken by Colin Kaepernick in his NFL protests.
Dr. Dre also used the lyric requested he refrain from, but nothing should be surprising from 2 individuals who have built their careers by doing what they want.
