Bulldog was a terrible promo man - that's pretty well known. I think his return could have been a mixture of a few things:
- Vince had a lot of respect for him and the Hart family, deciding to give him employment after WCW fired him.
- Vince wanted a link to the Hart family in his company, as it was a damage limitation after Owen's tragic death at a WWF event.
- It could kind of make the Montreal incident seem like Bret was in the wrong.
