Regarding the issues between Steve Austin and Vince McMahon, they are said to be related directly to Austin’s live podcast on the WWE Network with Triple H that aired back in early February.
Vince was apparently not happy with some of Austin’s questions for Triple H and while we don’t have specifics yet, The Wrestling Observer Newsletter speculates that it could be Austin asking Triple H about Chyna going into the WWE Hall of Fame one day. That question really led to Chyna talking about Triple H on YouTube and then making the assault allegation in the interview with Vince Russo. This then forced Triple H to issue a statement and got the company some more bad press.
When officials wanted to bring a podcast to the WWE Network as a part of their new programming initiative, Vince wanted a new host and he chose Chris Jericho. As noted, Jericho’s first podcast airs this coming Monday after RAW with United States Champion John Cena and based on the preview that was released this week, there’s already a lot of speculation that it will be much more company-friendly than the previous two podcasts with Austin were.
