#1 The roster is far too stacked
SmackDown's roster is superior to RAW's. While RAW may have a slightly stronger women's division, the word "slightly" is key here. As a whole, it certainly feels like SmackDown has the biggest stars and that's only to be expected since FOX is throwing more money at WWE, which means that they're entitled to a better roster.
WWE needs to protect a whole crop of Superstars and SmackDown contains many of them. It's going to be tough for them to protect all of them, but without a doubt, there will be more SmackDown superstars protected than RAW.
One such example from RAW who they can afford to not protect, for example, is Seth Rollins. The storyline he's in now is one where he's in a downward slump, which means that he can easily be pinned clean by a top SmackDown star such as Roman Reigns or Baron Corbin. The same can't be said about many other superstars on the red brand.
It's going to be interesting to see how WWE handles the entire situation. Either way, they can't afford to bury SmackDown the way they did before and NXT is a brand that should ideally be benefiting out of the PPV. Will WWE do the right thing?
