The answer would be "yes", if Vince McMahon gets his way. But even a man as powerful as McMahon, to paraphrase The Rolling Stones, can't always get what he wants.
According to DailyWrestlingNews.com, McMahon was trying to convince Bryan to be involved at WM32 in a non-wrestling role while they were all in Seattle (where Bryan officially announced his retirement on RAW).
Obviously having Bryan at WM32 - in any capacity - would be big, given just how popular he is with the WWE Universe. However, the talk among people is that Daniel Bryan is done appearing on television for the time being.
We all know that things can always change, but at this time it doesn't look good for anyone hoping to see Bryan involved in WrestleMania 32 on April 3rd.
