I'm going to stick my neck out here with pure speculation. (READ: This is my disclaimer that what I am about to say is only my opinion and not to be taken as anything remotely close to fact)
I'm a Human Resources professional by day. I do quite of bit of interviewing and occasional investigative inquiries for harassment. Meaning while still an "amateur" I am competent in "reading" people and situations.
With all that being said, at about the :55 second mark during Gaten's interview, he was asked about Tucker returning. Gatens non-verbal and verbal reactions make me a little nervous. First, Gatens flinches, and then comes up with an answer "yeah". but then quickly "retracts" saying “I would think so.... I don't... I don't know." and begins looking away from the reporter.
This raises a red flag for me. I don't read into it that Gatens knows for certain that Tucker is gone. But, despite what Matt said, I don't believe he is confident Tucker is coming back.
