How awesome is it that Big E did the announcing for Shawn Porter before his title fight with Errol Spence Jr. (Porter got beat though)? This opportunity probably came for Big E because, even if the Pay-Per-View event was not directly put on by FOX, it was closely affiliated.
WWE is obviously beginning their relationship with FOX starting on October 4. The event also took place from the Staples Center in Los Angeles, and that is coincidentally the location SmackDown will emanate from on October 4. Big E may also have a future in announcing when he wraps up his WWE career (just saying).
