#2. Best: Apollo and Big E's feud on SmackDown
Big E and Apollo Crews are two young and hungry stars on SmackDown. Both men find themselves in a great spot, and they're making the most out of what has been given to them.
Apollo Crews' attack on Big E a few weeks ago led to his first official heel turn in WWE and the emergence of a new character. This has added an edge to him, and the assault added an edge to Big E as well.
Big E defended the Intercontinental title successfully against Sami Zayn on SmackDown this week. While Zayn expected the Intercontinental title win to be the "perfect" ending to his documentary, he didn't get what he wanted.
Post-match, Apollo Crews snuck from behind and assaulted Big E again, standing tall over the steel steps. It was a huge statement made, and we could argue that it's the best and most consistent feud on SmackDown right now.
Apollo Crews may lose to Big E, but as long as he walks out looking better than before, then it doesn't matter.
