Re: Dean Ambrose, Kassius Ohno & Seth Rollins.
They're holding out on Ambrose until the "right" moment (so they've likely missed at least one of those).
Rollins isn't that good.
Ohno hasn't been in developmental for long, but it might have something to do with the way his body looks. Maybe they're waiting until he gets some more definition. Or they didn't want him sabotaging Cesaro's push by bringing in "old team" baggage.
