The roster should be fine.
Reigns and Cena will probably be picks 1 & 2. They're basically the same guy, after all; babyfaces that are hated by half the fanbase and can't be pinned by normal means. Vince probably masturbates over the idea of them BOTH dominating WWE programs.
Past them, there are a herd of guys that can be moved back and forth between main event and upper midcard.
If they don't do this, things are going to get tight when the Wyatts return and a lot of guys are going to be left off. A split would really benefit wrestlers like Sheamus, Neville, and Breeze.
What would really be interesting if they called out "Samoa Joe" or "Finn Balor" during the draft. American Alpha is probably ready, too.
The women's division is more complicated. Bayley will probably move up but I'm still not sure they have enough quality wrestlers. They might work both shows. On the other hand, Sasha and Becky could both be top babyfaces. It's too bad Emma got hurt.
