The part where he talks about people coming over when their contracts are up, of course that'll happen. What will also happen that was not mentioned (he probably wasn't asked so why bring it up) is that people will have WWE contracts expire and they'll leave for the other company (that is financed by the guy who owns the Jaguars and a bunch of other stuff).
And with regards to not benching people... Yeah that's kinda no. If we exclude the people who have been off TV for a short while (Sheamus, Nattie, Wyatts/Alexa) there are still people that have been absent for an obscenely long stretch like Omos.
